Auxiliary Stereo Input Hack
ฝัง
- เผยแพร่เมื่อ 17 ธ.ค. 2024
- Here's how to tap into your car's radio to add an auxiliary sound input, so you can connect your MP3 player or phone.
There's no need to replace your age old cassette deck for a cheesy looking aftermarket unit. Forget those FM transmitters, and cassette aux adapters. Wire the aux directly to your car's internal sound circuitry to get crystal clear CD quality sound!
The best part is, all you need is a 3.5mm stereo cable, which costs $1 at the dollar store!
This video demonstrates the addition of an aux line on a Toyota JBL Stereo from a 1999 Toyota Solara. Model # Fujitsu Ten 122000-09200101 or Toyota part number 86120-AA020.
Also illustrates the process of removing and installing the stereo from a 97-01 Camry and 99-03 Solara.
The hack relies on being able to trace the output from the tape deck to the equalizer. Solder two R&L wires to the output pins of the equalizer chip, which in this case was clearly labeled on the motherboard. Use a 3.5mm stereo extension to route the wires outside the stereo into the console, where you can connect an MP3 player, phone, bluetooth headset, iPod or iPhone.
Enable the tape or FM radio mode to open the auxiliary port. Mine will automatically over-ride the audio coming from the FM source.
On some cell phones with jack detection (such as the Samsung Galaxy S5), the radio must be off before the phone is plugged in and the music is played. Otherwise, the phone won't detect a headphone plugged in and you'll hear the FM radio plus lots of static.

Who else came here thinking they would do this, but changed their mind after watching the video?
it easy dude. Nothing special.
@@dieselgeezer18 maybe so.. but it's way easier and in many ways better to install an aftermarket radio.
@@Jimmy-rd5ig in some cases you can't install an aftermarket adio because of the way the radio is mounted, or you just want to keep the original, or you just want to be cheap
@@Jimmy-rd5ig People who do this like OEM parts and how they look. I don't want a space ship in my dash.
Haha
I just did this to my 2000 toyota camry with non JBL Radio. Your insight to soldering the right connections on the motherboard were spot on. It overrides the radio just like you said it would!!
I posted a gig on Craigslist asking anyone to do it for me, no one wants to do it. I have zero experience but i did it myself by following this great video. Thank you so much for sharing !!
+أبو الجوري Thanks glad it worked.
Hey, Just wanted to say thanks. Your videos helped me to do this and saved me $100 or whatever it was to buy a headunit. I watched all your aux hack videos before attempting to do this. It was also the first time soldering, much easier than expected.
I connected the Aux jack to a bluebooth car kit and now everything is wireless and hands-free in a 90s car. Thanks!
+PancakePlease good to know, I would like to do a Bluetooth aux hack video soon, did you need a ground loop isolator? Where did you power it from?
I bought this www.amazon.com/SoundBot-SB360-Bluetooth-Hands-Free-Streaming/dp/B00RH29CJO/ref=sr_1_3?ie=UTF8&qid=1523298051&sr=8-3&keywords=soundbot+bluetooth+car
basically I did your aux hack with a female aux. Plug the Soundbot aux male into it, plug the wires in the 12v adapter, wired it all behind the dash. It connects automatically (with the option to turn it off if you like), has a mic for voice calls, and is set to Tape mode on my headunit.
I needed a ground loop isolator for the aux cable without bluetooth otherwise there would be a faint buzzing noise when turning up the volume.
Legendary solution. I have been trying to find some "proper" way to do this for a couple of years!!! Great video.
+Nathan & Carol Vomiero Thanks. Glad you found my video
me: this looks easy enough *flips car and destroys radio completely *eh I guess I didn't do something right
+laziboi519 Try it
speedkar99 I just bought a Bluetooth transmitter instead 😂
I bought a new stereo for my car but I havent installed it yet. Im thinking il give this a try because I really like the stock toyota head unit that I have (its a japanese import one, cant find any info about it online). It looks nice, and it has a minidisc player. If I stuff it up il just install the new stereo, if it works then im happy and i'll sell the head unit I bought :D
Haha. This is me ^^^
recently I bought a LED clock and thermometer to match my red and blue light theme. I definitely suggest doing so. Its nice during the winter months when checking the roads for ice, and it checks you battery which I am constantly runny dead.
***** A cassette adapter will have too much static, hiss and clicking. Adding an aux wire completely eliminates that.
speedkar99 You should try putting a cassette deck adapter (a tape that will loop indefinitely) while playing that input with the AUX you have. I bet it will sound much louder than trying to override the FM radio with your phone/aux input. Plus you reduce the likelihood of making your stereo become deaf.
No way. The cassette adapter has too much noise, hissing and clicking. The sound I get is CD quality. Its been two years since I've done this mod and no issues. Since I tapped into the cassette deck audio signal before amplification, the volume would be exactly the same.
speedkar99 Please re-read my post. I had a feeling you'd skim it and misunderstand it.
So your saying having a blank cassette play and loop while playing the AUX from my phone? What is the theory behind that making it louder and letting the radio last longer?
Well not just a blank cassette but like a tape deck adapter cassette where the player can detect the cassette but have the adapter head on the cassette removed so that the player can't actually listen/read from the cassette, just turning the wheels and gears. Some cassette players are sensitive and will spit out the cassette if it thinks the tape is jammed or broken (spins too easily) which is why a tape with no gears or tape won't always work.
Anyway, as for the theory about the radio going deaf. Anything with radio receivers, if too much power comes in, overtime, much like human hearing, being exposed to a high amount power can cause the receiver to become less sensitive and therefore like a form of deafness. My thinking was that by having to play the music loudly through the phone, it could be too much power in an location that wasn't intended to receive.
Now if you go back with the cassette playing, because there is nothing touching the read head while the cassette is playing, maybe you'd have to use less volume, and therefore not only give you more room to raise the volume but also you wouldn't risk making the radio receiver go deaf.
Thank you..... I've been scouring the internet for hours searching for a wiring diagram... and this short cut is bomb!
+Justin Hall glad it helped. All the best on your aux hack, many radios are similar
hi thank you so much for this. I thought you soldered the tape player output so you'd have to put a tape in to play from the aux, but it looks like you went the FM way. I have the same radio and i want to do exactly what you did. again, thanks a million. this is awesome.
Glad it could help. I did solder to the cassette, but it just happens to override the FM signal automatically when I plug in my phone.
@unchboy
You can't just tap the speaker wires as the signal is already amplified coming out of the headunit. You need to tap into the unamplified signal inside the head unit, otherwise the sound volume will be very low.
I give you props for going to this length to do this but, I think it would just be easier to purchase a cheap aftermarket head unit that has BT, USB, DVD, and what ever else it has
But that doesn't have the look of OEM
Awesome video. I just got a 1999 Toyota Avalon. And was getting annoyed that I had no input for music... Awesome video. I subscribed to your channel.
+charls seal Thanks.
Just completed this mod on my 99 Solara.. Worked great. Thanks for the instructions!
Glad it worked out for you, now you can enjoy the most of your JBL stereo :)
The audio quality is much better than running it through a hissing, clicking, static laden cassette.
You could try opening it up and seeing if there are L&R points that you could solder to.
With the 2005 Camry, you have aftermarket options like ipod and aux adapters. I believe some 2005-06 Camry's came with AUX as standard equipment.
It should be exactly the same. Solder the two wires to the L & R marked on the board and connect it to your aux jack. Test it out in different modes (some require you playing a tape for it to work).
Hey buddy... I did it in my Toyota Prado 1998 serie 90 car stereo and works like charmed.... The stere different a bit but same structura and component DOUBLE DIN, You are a genius.... Thanks for sharing and make other happy...
Thanks for the feedback, I'm glad it worked out for you and its good to know that it works on other Toyota radios.
Neat hack! This is much simpler than the route I was going to take (replace stereo with Android Auto system).
+Elliott Partridge that's a whole different ball game, but a pretty cool project. You could also go with a tablet embeded
great how to! I could get audio through the tape source but only with an actual tape in there - which makes a clicking noise because the plastic cogs are broken. If only there was a switch i could solder to tell the stereo that a tape is installed without actually having to have one in there.
Thanks again
+Cameron O'Loughlin Yes I had the same issue on my brothers Lexus gs300 radio. He ended up going thru the CD input and playing a blank CD to force it to read from the CD input. CD doesn't make much noise.
Hello, I watched your video about a year or two ago but haven't had the courage to try this until now lol. What is the ground wire for and is it from the aux cable? It looks like the 2 wires you soldered onto the board were separate wires that you can buy from a hardware store, does that make the sound better or is it optional? If it is, what size wire should I buy and does it matter if I use the kind with smaller wires or a single solid wire? Also, I'm new to soldering but I bought a cheap starter kit to do this project. I can just use a push-in connector instead of soldering the wires to the aux cable? (Do all aux cables have a ground wire in them? What difference does it make?). Thanks.
Solder is the best bet. Those were just hookup wires...no need for them as you can solder the plug direct.
Just found this after I did something similar. I grabbed a small 3.5mm female audio adapter and I drilled a small hole next to the DISC emblem and drilled through the inside plate then ran it down to the board. Works well you did it long before me, but I have the same head unit in my AE86 and SW20. Like the stock Toyota look.
Yea the stock look is classic. Glad it worked out for you
I usually use a cassette to auxiliary tape for my music. You can find at dollar store, radioshack or similar (I think that went out of business) or order on Amazon. They range anywhere from 4$ - 20$. I usually get one for 5 bucks.
DJ DamnSelf yeah but you have the audio degradation that comes from uaing a tape adapter...
Robert Hollar Not at all
@Syed Khalid
It should be the same as the tape deck stereo since your soldering to the tape's L&R ports anyways. Yes, a female aux jack can be used, but you'd still need a patch cable to run to your MP3 device.
Thanks for posting this. I just finished the instillation on my 2001 Land Cruiser and it works great (Toyota part number 86120-08130). Very similar head unit to OP's but slightly different. I didn't solder to the correct ground the first time so the sound quality was terrible. I found a pin nearby the two test points that shared a connection with the sony chip ground and that solved it.
Great
I have this exact car model with this exact same radio face. But when I opened the radio the circuit was completely different. I am about to look if I can trace the tape deck pins to some post equalizer solder points.
It should be the same in theory
That's too much shit for me lol
No joke hey
Sorry for the comment on the really old video, but doing the same thing in a Hilux. If you had removed the springs in the cassette tape leaving it in the “loaded” mode. Would the tape mode work to turn the aux on?
Yes but the motor also has to be turning so a real cassette does the job better
Can you please do an aux cord hack for an old headunit that only has a casette tape option on it? It would mean the world to me. Thanks!
+Isaiah Garcia that's exactly what I did here, I went thru the cassette lines that eventually led up to the radio lines.
Look up my Lexus aux hack I did another video thru cassette as well
speedkar99 I just finished watching the lexus aux hack video. The thing is, when I disassembled my headunit the other day, I couldnt see where I should solder the aux connections. Im not that good with electronics to be honest. Its an old kenwood headunit. If its not too much to ask, can I send you pics of the headunit disassembled and tell me where to solder the aux connections? And is it possible to trick the headunit that theres a casette in it instead of actually having one in there? The lexus hack required you to have a casette in it. I hope you can help me out. It would really help me a lot :) thanks!
+Isaiah Garcia how about the fm board? Any leads there
speedkar99 not really. The things is, I dont see any "R" or "L" to solder aux points to. The motherboard hardly gives any information about the connections. I'm not entirely inexperienced when it comes to audio configurations but man this aux hack thing is making me feel stupid asf. And it sucks bc theres no way I can afford a new headunit within the next couple of years. Or atleast until I finish college and get a job. :(
Have been in there 'deep' as you before - however, would inquire if there is any way to use that other 'plug input' on the back (like, what is it? Why not used?) with an adapter to obtain an input?
Yes but you'd probably need a emulator
Loved this video...
I was looking for 1hr how to connect but finally coz of this video got success full
Thanks heaps for posting this video
Awesome glad it helped
How did you know the input reference impedance for the tape deck's amplifier would match the output impedance of your phone (I assume it's 50 ohms)? Or did it? I know from experience that running such a low output into a high impedance input (op amps tend to reference around 1k ohms, as I recall) introduces a lot of noise. I'm considering trying this; I just want to make sure I do it right the first time.
+Mick Mathews I didn't test the impedance, I just tried it (at low volume first to make sure) and it worked. I've been using AUX for more than 2 years now and it works great.
So I’m about to perform this myself on the same radio unit, is there any problem just soldering the AUX cable directly to the pads? And is there a way to make sure the L and R channels are correct? Awesome video btw!
on my 99 Camry i took apart the front on the stereo. released all the green LED's and replaced them with red and blue. 10 out of 10 would recommend!
Danté Smith Looks good, I changed mine to white:
th-cam.com/video/i3lrdih-6V8/w-d-xo.html
I'm trying to solder the AUX input onto my 2004 Toyota Camry stock stereo, but on the motherboard of the stereo, there is very minimal labeling of the solder points. I have no idea how to proceed because I'm not sure which one to solder to. Anyone having any suggestions would be greatly appreciated!
+sunnyhaibin Follow the leads from the cassette deck. There are usually 4 or 8 wires that come straight off of the head for L and right positive and negative and ground for each.
+speedkar99 From the ribbon cable slot or the one you plug in when you put the cassette deck back? The one at the bottom of the cassette deck has 14 solder points but none of them are labeled. How do I know which one to solder on? Thanks!
+speedkar99 I checked the ribbon connection on the motherboard (similar to the one you have at 3:44) and I found 6 pins under that socket. Are those the pins you were talking about? If they are the points, how do I distinguish them as L, R, and ground? Thanks!
+sunnyhaibin Skip to 2:15 in this video where the cable comes from the cassette head and goes into the board.
th-cam.com/video/zp-t7cl_ZSs/w-d-xo.html
Many stereos have L & R markings, if not on the immediate board, then on a sub board which you can back-trace with your continuity tester.
+speedkar99 So you suggest that I should solder the points onto the cassette deck board instead of the stereo board? Thanks for the reply!
Have you considered using the L/R pins on the 12 pin connector on the back ? Shouldnt that be the same, but without opening the unit itself ? I have a 2002 Corolla with a W58802 unit and was searching for a way to add an aux input (possibly 3.5").
+Spalxy I don't think all radios have a CD changer port. Either way you'd need something to fool it to read from the CD changer port, like a module, or CD changer.
Yeah, i was afraid of that, was unable to find a "simple" method of just telling it there is a cd changer (like adding a resistor or something simple) and hijacking just the audio pins. There are a few projects on the net, but they are too complicated for my needs. Either way, thanks for the reply :)
+Spalxy yea ive looked into them, they emulate CD changers.
Yes. I've stumbled upon this project www.softservice.com.pl/corolla/avc/simpleaux.php which has an AUX only option and should simulate a CD changer's presence just so that he can use the audio inputs, but still looks a bit over-complicated.
What Store Can I Get An Aux Input Installed At?
with a whole new stereo
The two wires you soldiered to the left and right ports to the mother board, were they just normal wires you had ??
+axel marcelin Yes, just normal patch wires
This looks like a great option. I'll have to see if there are L&R solder points in my Avalon's deck. If not I guess I could use the L&R input leads that used to connect to the tape deck, which is long gone.
I think most radios might have the L&R points, some may not be marked. The tape deck will work, but it won't be amplified, pickup some noise from the head, and you'll have to trick the cassette player into playing an infinite loop.
how about just soldering to the wires coming off the tape head? my mobo is different, and cant make sense of the tracers on the board.
+Steve Me yes that works
So all I have to do is find the left and right testpoints on the main board and stick the left and right cables of the aux cable? and it works like a normal radio with fm etc but when the aux is connected it plays music from the phone?
+NaiReEimaiKyprios yes and don't forget the ground wire
speedkar99 what happens if i dont connect the ground wire?
what is the cable removed at 1:58, before the antenna cable. it looks like a 3.5mm cable.
Hi do you have you have to disable the airbag when doing work around it , like touching wires or doing speakers ?
+westsidecartel90 No, the stereo isn't near the airbags.
Great video showing step by step instructions. Is it possible to add auxiliary to six cd changer in glove box. All factory. It's an older lexus.
Thank you
Tom Harrison Thanks for the feedback. Yes it is possible to many vehicles. I've also added aux to a BMW E39.

I did this on my 05 4runner and ran into obstacles... The FM radio is not bypassed when playing through the new auxiliary cord. The only way it works is by activating the tape deck, which stupidly is only possible by having a tape inserted. While I am able to get high quality sound through the audio, my tape deck makes super annoying noise when playing! Little tics and squeaks from the mechanism operating the tape. When I look at the stereo mother board I have no idea what I'm looking at... Is there any way to easily rig it so the tape deck is activated without actually inserting a tape? Or maybe the FM radio has L and R soldering points? I don't need FM or AM radio ...
Try turning off the radio, plugging in the phone and playing music then turn it on.
Or you can play with the limit switches inside the cassette deck to trick it in to thinking there's a cassette tape in the deck
youre a star but i'm wondering how many parts would be left over when I finished screwing it back together
At least 4 screws
lol
@LondonxParis
You can still play radio until you plug in your device.

speedkar99 i have the same car 99 toyota silara sle with jbl and i want to do this aux hack but did yiu use one single length of aux cable or did you splice aux cable into another cable to get the length to reach from headunit to where it is now?
+david anderson In the video I spliced the cable to make it easier to run the wire out of the stereo case, and then joined my aux cable to it. You don't have to do this and can connect it directly.
where did you get your aux cables from they are different then when you strip a 3.5 cable the wires are very thin copper and not individually rubber coated. did you use wires from a wiring harness?
+david anderson the aux wire is a stereo extension cable from the dollar store. The patch wire was chopped off a computer power supply.
Great video! I have a 1996 Land Cruiser and I was able to follow your video to get the radio apart and access the circuit boards. But it is obviously different than your Solara and I don't see any points clearly labeled R and L. Any suggestions? could I send you a picture of the boards and maybe you can identify?
+Michael Schaller Hmm did you try the CD changer?
Sometimes it just takes trial and error
I did look at the CD changer but also didn't find any clearly labeled points called L and R. After looking more at what I think is the motherboard I found test points (TP200 and TP300) labeled L and R. They're next to some pots. Can you look at this photos and see if that looks right? Also what do you mean by trial and error? Just try soldering the aux cable to them and seeing if it works?

+Michael Schaller Yes sometimes you have to try soldering and see what works. You can send me links through a PM, I can't open it here.
what did I miss..you point out 2 points on the main pcb, but I thought I saw like 4 wired coming out of the radio...where do they go??
+broderp 3 wires. One for the L channel, one for the R channel and one for the ground.
+speedkar99 and where we have to plug the ground cable??.
Screw it into the body of the radio.
I have a question i took the factory stereo harness off a long time ago.
Just now i want to fix it. But everywere i look there mention wire that i need to hookup to the stereo but they are not on the harness of the car
+William Ramos Some of the wires are not needed, especially on aftermarket installs. Connect the stereo and see if all the functions work properly.
I have a 94 Lincoln Mark 8 with attend disc CD changer and a tape deck I want to do something like this but keep the existing systems functioning. Do you have a solution for this? I guess it's just a matter of connecting the tape heads and living with the hiss sound?
hey, I did this yesterday and its working great, thank you. but it only works when theres a tape in the deck,it doesnt work on FM radio like you said. and when theres a tape inside the sound from the tape overlaps with the AUX sound, a bit lower in volume but very obvious. so what i did is i got one of those cassette to aux adapter and cut the wire and use it in the deck. do you have a better idea? maybe trick the stereo to think that theres a tape in the deck?
FM override seems to work on only some radios You can disconnect the traces of the cassette player so you don't get interference.
+speedkar99 how do i do that.
+kmmdur Trace the wires coming off the head of the cassette deck to where the ribbon cable attaches to the board and disconnect it.
nahh... thts too much for a common user like me !!! but for techi people is a good video.
Ah, its not that hard, common. Just 3 wires! You can save alot instead of buying a new ugly aftermarket radio.
Agree
its not hard. You just connect a few cables. Its not rocket science
I wonder what year Toyota this was . A Camry I assume.
MAD!! How you even came up with that is pre smart bro.
A lot of background research and trial and error.
"I'm not sure on the balance issue, unless you soldered to the mainboard which separates outputs to the individual speakers instead of the cassette deck which is just stereo sound."
So which I was supposed to solder the wires... I believe I soldered where you soldered since you and i have the exact same radio... which was @4:18 in your video...
I believe I did NOT re-insert the tape cassette wire to prevent static pops..
Is there any way AROUND the problem of your statement below...
"you need to turn the radio off, plug in, press play on the phone, and turn the radio back on again, and then repeat everytime you change tracks."
Thanks again!
+jlhouse6 So does it work when you unplug and connect? I haven't found a solution yet, I've just been using it as is, my tracks are 20-30 mins long anyway. I suppose I could try another app or ROM on my android, or just go back to my old original Samsung Galaxy S.
Connected the aux wire to inbuilt fm modulator and the voice quality is too bad. How do I rectify this :/
And if I connect aux directly to L and R of cassette player will it sound any better than "cassette-aux"?
Yes it will be better quality because its direct to the equalizer and won't have the static and hiss of a cassette adapter.
Hey man, do you know anything about how I could install an after market Pioneer radio. I can't find the wire schematics for that JBL wire so I can splice it into the connecter for the pioneer radio. (2:05 is what I'm talking about)
You need a wiring harness specific for your car to convert the spare connectors shown in the video to wires that your Pioneer stereo can connect to. I don't recommend splicing directly into the car wiring. See my Pioneer stereo installation video for details: CAMRY Pioneer Stereo Install
Great video. Just wanted to clarify, you soldered the L and R channels to the main board but what about the ground coming from the jack? Is that the one you screwed on?
Thanks. Yes the ground is the one I screwed into the chassis of the radio.
You have done well.I will have to replace the fujitsu 10 radio/cassette/cd as there is a black smudge on the radio display in my 98 Camry.Plus the Cassette is naff.Pity.It has worked well and sounded ok.Pity.I presume the FM modulator was hissy? Thanks.
martyw34 FM modulators could work as well. The FM transmitter was horrible. Adding an aux wire is much cheaper than both with much better sound quality.
martyw34 As for the LCD smudge you probably could just replace the LCD itself from a working unit. Check this video on how to take it apart: th-cam.com/video/i3lrdih-6V8/w-d-xo.html
Ok thanks.And you are have done a good job on extending the useful life of the Camry radio.Which I think sounds ok.Normally,years ago in the 70s-it was the first thing you did was to replace the basic standard radio with aftermarket.
Yes, my first thought when I got the car was to replace the radio with an aftermarket unit with AUX/ USB input. But after successfully hacking an AUX cable into this system I don't have a need to upgrade the head unit. The JBL system actually sounds decent, especially for a 16 year old car.
would this process work for a Pontiac g6 stereo? I was thinking of of connecting all 8 speaker wires to to and rca to audio jack cable. but idk if that would work.
+Joseph Lagunes Most likely. As long as it has a tape deck with that analog input. If its only CD, you can try looking for L & R ports on the circuit board for that.
+speedkar99 thanks for taking the time to reply... awesome video.
Thanks
Very excited to try this. Have the same radio unit in a '98 4Runner. Thanks, man. Just curious if you can explain the theory behind how this works a little more. Also wanna make sure I understand... So if the car unit is on FM mode and the phone is not plugged into the aux cable, the FM radio will be heard through the speakers, but if the car unit is on FM mode and the phone IS plugged into the aux cable, the FM radio signal is completely muted and the aux cable signal is the only thing that's heard through the speakers?? And it comes through in stereo? And the FM radio doesn't start to play if you pause your aux music?? It only starts to play if you unplug the aux cable? Just from soldering those two wires and connecting ground?? That sounds way too good to be true. Am I understanding this correctly?
How tf does the car unit know to stop listening to the FM radio and start listening to the aux signal just by having the phone plugged in??
+Nick Brumme The phone overrides the FM signal. It also depends which phone your using, the scenario described was how it worked for my Samsung galaxy s1. For my s5 you have to press play on The phone first then turn the radio on, otherwise you get interference. Has to do with jack detection I think.
speedkar99 jack detection doesn't explain the full picture as the jack detection would be on the phone's end of the cable, and this is just a TRS jack sending L & R channels of audio from what I understand; I'm curious how the car unit knows to switch what it's listening to.
Anybody else have any input?
How can I guarantee my phone (or any phone) plugged into this new connector will mute the radio even when there's no music playing?
The cable I soldered didn't have an insulated ground wire. It had a bare stranded wire, which I did ground to the same spot as you did in the video. Do you think that could be causing me a problem? It makes loud pops and static in between songs. You can also hear the radio in the background behind the static.
Yes a bad ground might cause the static and background radio. You need a clean strong signal to over-ride the radio. If not, try running it in TAPE mode with a blank cassette. Mine over-rode by shear luck as essentially I soldered it to the TAPE deck wires.
I occasionally get loud pops when I plug and unplug my phone.
First, i just want to thank you for this very very thorough video. The only part that I found confusing/ambiguous was the aux-in portion of the video.
My questions are:
I purchased a male-to-male audio extension... Correct me if I am wrong, but I should cut one end of the wire and I should find 3 wires in the STEREO audio extension, correct?
I solder 3 wires (red, yellow, and black) to the audio extension cord I cut. The OTHER end of the BLACK ground wire should be screwed in as shown at 4:30. The OTHER end of the RED wire should be soldered to L, and the OTHER end of YELLOW wire should be soldered to the R.
Is this correct?
For the radio soldered LEDs... by any chance do you have a youtube tutorial video on how to change the LEDs? especially the backlight LEDs for the radio display (i have the same exact radio as you).
Again, thank you!!!
Your wiring is correct. Did you get it to work?
I'm working on the radio LED mod. I've ordered in the SMD LED's and will go from there.
speedkar99 I am going to do the aux-wiring... but currently am doing the LEDs for the radio.. Below is a link that sort of helped me but due to the fact that the pictures that were posted no longer work I cannot determine the polarity setup for the radio.
www.toyotanation.com/forum/107-camry-solara-lounge/97347-diy-stock-stereo-led-color-change-lots-pics-56k-no-way.html
Please keep in mind for the above link, the radio backlight seems different than mine (I say "seems" because again, i cannot see the pics and for me the radio backlight ONLY is actually a SOLDERED BULB (NOT LEDs as mentioned in the post)). For the soldered bulb, I removed it and will TRY to solder a LED in its place.
For my radio... on the BACK of the circuit border I do see 2 white squares... there is one red dot in each square. One red dot is at the bottom-side of one square, and the other red dot is toward the right side of the square.
I am ASSUMING that it is a notation stating that for the LEDs, the negative polarity should be facing downward or rightward... since there are LEDs that are soldered horizontally and vertically.
What I've been doing is soldering a few LEDs and going back to my car (with the radio) to test if the white LEDs work (since I have no idea how the polarity should be aligned). This is my first time soldering so I do not know if I am doing it wrong or simply have the polarities wrong... none of the LEDs I've added seem to work when testing it on the car...
I know you said you were going to order the LEDs, but when do you think you're going to do a tutorial for the radio LEDs?
Again, thank you very much for your help, and sorry for the super long reply!
Okay so let me get this right, your radio (which is the same as mine) has bulbs for the backlighting???
Ive taken mine apart (as well as a few like mine in the junkyard) and they all have small SMD 1206 LED's, with the exception of a tiny incandescent bulb for the LCD display.
If your LED's aren't working it could be either polarity or a voltage difference. The bulb you replaced might operate at a higher voltage than the LED you put in there.
Can you please document your work with photos, it would be a good guide.
I'm still waiting on my LED's to come in from eBay, they usually take a month from China.
speedkar99 No not bulbs.. but one bulb... just like how you stated
"Ive taken mine apart (as well as a few like mine in the junkyard) and they all have small SMD 1206 LED's, with the exception of a tiny incandescent bulb for the LCD display."
My problem is I do not know how the polarity is setup for the LEDs... that's why I was asking you if you know how the polarity is setup because this is taking much longer than expected...
As a test run for the LEDs, I've soldered some with the negative pointing to the left and other LEDs soldered to the right to see which polarity is correct but NONE of the LEDs are lighting up..
Do you know how the polarity is setup for the LEDs?
I can't tell you off the top of my head without experimenting myself. The best way is to learn by checking the polarity of the stock LED's (with a separate 3V power supply) and applying the replacement LED in the same direction.
Remember, these LED's are wired in series, so one that is wired backward in the string will cause them all to not light up.
need your advice AGAIN lol on the radio situation. i was resoldeering the connect points. the reason being switching out aux cables. and in doing so i had the radio down to just the main circuit board and to test if both sides of speakers where working . i had the board plugged in and just the face plate on to control the radio. and in doing so some of the solder points must have touched a piece of metal because the radio shutoff . and i mean shutoff like the cassette tape wont resond or cd playyer when i connect everything .. idk if that could be a fuse? or if i now need a new radio ?
+david anderson I'm not sure if the radio has a fuse internally. But yes that's the first place to start. Next, examine the motherboard for signs of burned components, swollen capacitors, or open circuit, especially in the area where the power transistors are. If you have JBL keep in mind the amp is behind the glovebox and can check that too
I figured it out .. but i think after so many trial and error the solder point for the left and right is no good i cant get solder to stick and everythings a mess aka melted around it lol . So unless theres a way to get the leads to stick to the motherboard or another contact point i think im screwed
@@anthonyanderson5635 next time you solder try to buy extra flux and have it on hand for your project. my early solders were a blob mess until i learned how to use flux better. there are lots of youtube tutorials on that. good luck with your next build!
Please help!!! I have a 99 Avalon took out the radio.. And there are no screws to get to mother board??? What should I do??
+charls seal No screws? It must be just fitted together then, you'll have to pry tabs and take it apart.
do you have the labeling diagram for the connection cable of Fujitsu ten n535
Sorry I don't, I just read the callouts in the circuit board to determine left and right.
Thanks for this i have a 2000 landcruiser with the same head unit.
I will be doing this tomorrow
Thanks
Hope it works out for you,
I got a 99 TLC does it work for you?
I see three wires coming out to the plug. You soldered a right and a left, what is the third wire for?
Ground
@speedkar99 Thanks a lot, so instead of adding a 3.5 mm cable i just get one with a female aux jack right? BTW I just have another question the orange lamps do not light up with my small lamps or whatever they are called. Is there a way to fix this? Thanks a lot
after I did this install my rear speakers do not work... I'm not sure if it is because my rear speakers just happen to die or the soldering effected the speakers... are your rear speakers working after the install?
Yes all my speakers work.
I just bought a 2001 Solara with the JBL stereo. The previous owner had something custom installed but removed it prior to selling the car to me. At 2:16 you mention the cables to the JBL amplifier, these are left unconnected in my car so the sound is very weak. I don't have the original stereo anymore (I have a pioneer). Is it possible for me to reconnect the JBL amplifier to the new stereo? if yes, how?
Your new stereo most likely has a built in preamp. It won't be compatible with the JBL. The amp in the headunit works to power the speakers through those connectors in the back of the dash. To reuse the JBL amp, you most likely need a JBL unit which you can pickup from a junkyard.
Thank you for your answer. It sounds like the sound is amplifed enough to the rear speakers however the sound in the big speakers in the door is very very weak.
(Also previous owner blew both of the rear speakers! :/)
It's a lot of troubles for a car I'm going to sell again when I leave for Europe in January..
That being said the rear speakers were probably replaced with ones of lower resistance, causing most of the sound to come out of the rear speakers instead of the front. Also check your fader settings to make sure the sound isn't setup to be dialed to just those back speakers.
If i do this, can i play music from radio, cd, and tape? Or it's only aux for ever?
+lCreatived Yes you can still use the other functions as long as your mp3 device isn't plugged in.
Can I ask which brand of wire you used for the aux-in wire itself? For Samsung phones and LG phones, when I plug in the aux-in, I only hear the car radio but with the volume slightly lowered by itself. I have no problems with an iPhone, or my Chromebook...
Also, not sure why but my BACK speakers of the car is SIGNIFICANTLY lowered... I have a 99 camry and followed the soldering as stated, but my question to you is by soldering the 2 wires to the left and right... does that some how effect the BACK speakers? I know the back speakers still work because if I use the balance setting and have all the sound going to the back, I can hear the radio whisper...
Any help would be great... Thanks!
+jlhouse6 Some cars won't override the radio signal like mine did. You could use a blank tape to trick the player into thinking there's a cassette in the deck and the radio signal will be overridden.
I'm not sure on the balance issue, unless you soldered to the mainboard which separates outputs to the individual speakers instead of the cassette deck which is just stereo sound.
I too found a difference in the phones. On my Galaxy S, plugging it in with music playing automatically overrides the radio, where as with Nexus and my Galaxy S5, you need to turn the radio off, plug in, press play on the phone, and turn the radio back on again, and then repeat everytime you change tracks. Annoying I know.
Quick question. Only have to connect Left and Right Channel? No ground no anything else?
+Adrián Castañeda Yes you have to connect ground to the shell of of the radio.
Where do you attach the ground too?I noticed you mentioned in your previous comment that you attach one to the body ,what about the other end of the ground wire?
Thank u
+Navid Etemadi i was making tests with my ipod and every time that i grounded to the body the ipod freezes and had to restart it. Look for one that says "A Grnd"on the board. The aux cable has 3 wires left ch, right ch and ground, those are the 3 cables you connect to the board. In my case i had to make it different as the round connector had left front, left rear, right front and right rear. I have two units, a cd changer connected to a cassette unit, in my case I connected the aux wires to the cassette unit and just played a silence CD and it worked great. Also i can play music only with the radio on but that way you hear both your music and the radio. Hope can help
Thanks a lot for taking your time to respond.
Yeah makes a lot of sense. I will update you incase I run into any problems.
I couldn't believe someone was doing exactly what I wanted on the exact same stereo head unit I have. I even have the same car! (US version)
The only difference between you and me is that I'm using the stereo, JBL amp, in a custom indoors setup. When I had to give up my integrated FM modulator, I was hoping something like this could be done, especially since the tape deck didn't work.
Cool, so does your AUX hack work properly?
Perfectly. I still can't believe this hack was so easy! Thanks again.
Could you do something similar with the CD rather than the FM signal ? So when you select CD mode in your player you can plug in the Aux and have it play through there ?
+ElectricRides Yes, same concept and just push in a blank CD and that will trick the player to read from the CD input.
Will the sound be limited to FM quality? I'd rather listen to full range tape with hissing than narrow range FM frequencies. Can you please clarify this?
I like the video. Very creative. My only concern is that when you leave it in FM mode, does it play the radio in background or cuts it off completely while playing iPod?
It cuts off the radio completely, as you see in the video.
Also what are you going to do about the incandescent bulb for the backlight/LCD display... ?
Most likely I will try to replace it with a 5050 SMD LED I get from a #74 bulb, depending on how the light diffuses behind the display.
In peoples opinion is the AUX better or the bluetooth option. I have a Camry '06 and trying to decide on which to either buy or do.
+dozierc Its a matter of convenience. AUX doesn't require much installation (assuming you're getting a GROM kit) and it just works. With bluetooth you have to go through a bit more background research and installation and pair it with your phone but then you get the convenience of it wirelessly playing music and answering calls. Audio quality is about the same.
speedkar99 Thx for the reply speedkar99.
Thanks for the awesome video! I have a quick question though, do you know if it is because I solder incorrect so the sound quality is difference when played on AM vs FM mode? Through the AM mode, the vocal or center sounds louder and is more quiet in FM mode.
I tried using an aux Bluetooth receiver but I would hear the radio in the background while the aux is playing, which is not obvious when connected directly with aux. Do you know if there is a workaround?
Thanks!
Hi thanks for the video just a few questions:
1. Is it the same operation for a radio with Tape Deck only
2. Instead of soldering the wire could i put a headphone jack that comes on newer cars
I'm planning to do this on my 2005 Camry, does using a shielded cable to aux jack eliminate noise?
+Honda 97 It should help but isn't entirely nessesary for car audio.
Let me know how it goes, I'm going to work on an aux hack video for my 04 Camry stock radio soon.
Ok. I have a 1999 as well. The Original wire harness that was going to the stereo, does that just sit there. I need this like right now
I am putting in a whole new head unit
george corsentino
Yes the harness that is behind the radio sitting there (in cars with JBL) leads to the speakers directly and bypasses the JBL amp. If your putting in a new head unit, you need to use these connectors with your stereo wiring harness.
I recently shorted out my jbl amp by accident. Do you think the radio went bad along with it? The 99 Solara amp is a jbl aa030. I tried using an aa050 out of a 2000 convertible and then an aa040 out of a 2001 Camry xle. They both fit but neither worked. Do you think it needs the same amp it came with? Or do you think the radio went bad as well? Thanks
+tigercat0924 I don't have much experience with amps and radio's. Why not just grab the same JBL amp from the same car in the junkyard and give it a shot?
Also, there *might* be a fuse in the radio that you should look out for.
I already disassembled my Toyota 2din stereo. Almost identical with yours but with different board. I cant find the left and right points to solder...
I just did this on my stero model# Fujitsu Ten 122000-50600101 I also have the R and L as shown in the video but the 2 adjacent ports next to where you left the cable to the tape player unattached (3:51) it says R-channel and L-channel. Are these the ones i'm supposed to solder the L and R connections to? I did it to the other set of R and L and it didn't work.
I just tried it to the ones I described and it was for the tape output. How do I tap into the FM output? The circuit board does not have it labeled.
Mine didn't have the FM output labeled, and I taped into the tape output as shown in the video. Unexpectedly, the AUX music from the MP3 player automatically overrides the FM music when I plug it in. You could try tricking it to stream music from the tape L&R channels by playing a blank tape.
Ya, the one I soldered the connections to were for the tape so I've been using the blank tape method. I have another set of R and L but they were not for anything, even blank CD.
I have one more request. Instead of a 3.5 male cable, can I use a 3.5 female pin so I can screw it on the panel? Do you think that it would work the same way?
Yes it would work, but it means you'd need another male to male connector to connect your AUX device.
but.. how do you stip the hissing from a tape deck aux cord without doing this?
+chill dude Using the tape will always give you hissing. Hacking the cassette deck with the head disconnected or a CD deck will give you clearer sound.
I attempted this on my 2003 Camry XLE with JBL 6-disc changer and tape deck but can't get it quite right. I'm pretty sure I did everything I was supposed to. Well, at first, I had neglected to do a ground wire and when I tested it, I got a tiny signal that was quiet and extremely distorted. So then I realized my problem and added a ground. But now it's still only very slightly better. It's not usable at all. It sounds like a radio station that's 100 miles away. And this happens even with the antenna unplugged, so it's not because of other interference. Is it possible that my solder connections would cause that? I figure if I'm getting any signal, then they are ok; but it wouldn't be the first time I was wrong.
My PCB is quite different than the one in your video, but I managed to find the only things that resemble the test points and they are labeled "TP4". Is it possible that those are not in the same place in the signal chain and they're coming in after the amplification instead of before?
As a side note, I can't get my tape deck to accept a tape. I attempted to put one in to see if I could get it to work that way after reading comments. But it's like the deck mechanism isn't working and doesn't react to inserting the tape. Thoughts on that?
Thanks,
Joel
I'm not sure about your tape deck.
Regarding the wiring, follow the L+ L- R+ and R- wires from the cassette head on your board to an appropriate soldering point using a continuity tester.
Joel Cook Hi Joel.Could you try a signal injector?
martyw34 I ended up just getting a new Pioneer stereo. Bluetooth, aux, usb, cd. It's quite nice.
Ok ta Joel.Good idea.Thanks.
Did you just purchase a generic AUX cable and strip the end? The end you soldered that is?
Yes
Your videos are very informative. I also have the same exact radio and wanted to do the same. In term of sound quality, would it be better if I use the CD input instead of using the FM signal? I understand that a blank CD is needed to play using this mod. My question is, where on the board do I solder the L/R in order to use the CD input. Thanks!!
+Hung Lam yep CD will work, see my other CD stereo aux hack vide I posted earlier this hear for details!!
I have after market speakers that were installed before I bought my 98 Camry. Will that cause any issues if I try this? Theyre a lot better speakers than the stock. I'm just nervous that I'm gonna fuck something up and have no music at all in my car.
+LiftedByChoice Nah the speakers shouldn't affect it
Alright. I just bought a cassette aux and it works pretty good. Except when it gets REALLY loud then it starts to fuzz out a little. But I don't want it that loud anyways because of the strain it puts on your alternator. Especially since mine is still stock somehow. Thanks for the info though. Maybe I'll give it a shot if I get subs or something.
what original car stereos won't this work on, excluding ones that have bluetooth or an aux input already?
Ones that don't have a tape deck?
Just purchased a used corolla, my issue is the same, but a lot of work to be done...
That is cool & I believe very doable for my skills. However, I want to add a headphone cable (end result being female), so that I can listen to stereo w/out bothering my wife, who is annoyed by loud music. Could the same principle be applied to this purpose instead? Will be using the smaller earbud type rather than a heavy set (or 'cans'). Is the process the same, provided I can find the adapter leads (preferably all in one kit)?
Would had been great for Toyota to include this on all 2000 models & up. Maybe they did with select, more expensive vehicles. Yet I love the sound of the stock JBL unit, the best I've had in an auto stereo, seems like they'd include a jack somewhere (obviously not looking at this video). In the past, I found a hidden cruise control module behind a pop out trim piece when cleaning my ride. Only thing needed was a new (the correct) multipurpose arm for the headlights & whatever else was connected, found in a junkyard for $10, once installed, the cruise worked. If not mistaken, a 1976 Dodge Aspen coupe, near 10 years old at the time. I presume this was a (quick) way for the dealership to add a few more hundred bucks to the price of car by swapping the left lever.
Yes you would solder the cable to the unamplified output of the speakers.
The only thing is you need some sort of a cut off for the car speakers
@@speedkar99 Yes, that's the tricky part! Especially being the car has the premium 6 speaker JBL unit with separate tweeters in the doors. There were two identical models on the lot with the same running gear & color. The main differences in ours, which was $1,300 more, was the inclusion of a powered 2 way sunroof (can tilt up or slide fully open) & the premium JBL stereo, that's the one I fell in love with. Too bad they didn't have BT in those days, if so, weren't offered by Toyota.
I could always consider the purchase of a new & more featured touch stereo that would include a jack (or BT) for private listening, as well as the inclusion of a USB updatable navigation system & no wire splicing. I used to buy my replacement stereos from Crutchfield, for an extra $10 or so, add an exact fit adapter so no splicing required. Maybe that's my best option. Can always get at least $50 for the stock unit, maybe more, depending on demand for these & supply available.
Still love your video! Will be on the lookout for more.
I just sliced my STEREO audio extension wire. I see a white sleeved wire, red sleeved wire, and a bunch of silver wires that were not sleeved....
Regarding your yellow, red, and ground wire... Can I assume I should solder the red to the red, yellow to the white, and black to the silver?
My wires were just patch cables I had, no need to match colors with mine.
As long as your ground corresponds to the ground pin on the 3.5mm jack, as well as L&R, you should be good.
The wires that are not sleeved is most likely your ground. You've got to do some trial and error to see if your red or white wire is the L or R channel and solder accordingly.
My aux cable only have red and yellow wire, so do I solder red to left and yellow to right? By only soldering red and yellow will the aux work with out ground?
You need a ground for it to work. You'll have to determine if the red is left or right with a multimeter and find a pin-out for the 3.5mm jack.
