I have a 2015 GMC Yukon XL Denali with the GPS problem, I ordered the antenna from Amazon for 61 dollars.
I followed the instructions from your video and replaced it without any difficulty.
I must say that I probably would've not have been able to do it without your very detailed instructions, specially on how to take apart all the covers and disconnects before I even got to the antenna.
I don't know how much money I saved, but here in New York probably close to $1000 at a GMC dealer.
I saw a couple of different videos on this, but yours is, by far, the very best.
I am no longer in the middle of a lake, according to the GPS with the bad antenna, I am now where ... I am.
Thank you so much for your help !!!
Thank you so much for your kind words. Glad I can help.
There are a dozen videos on this and yours is the only one worth watching, saved me $500 as well.
Thank you sir. That’s awesome you saved so much money!
Bought an new factory GM antenna with drain in front on Amazon for my wife's 2015 Cadillac Escalade. I'm going to use your video to help me install and save some money. Hopefully, I'll be able to get at the wire clips the 10mm nut without too much problem. Thank You for showing how to do this job!!!
It’s not bad. You can do it. You got this.
How did everything turn out, I’m going through the same thing with mine right now
Thank you for this I replaced my antenna in 20 minutes with your help and best of all my gps is now working
Good Job! And saved money too!
I found this video very useful, worked for my 2018 GMC 1500 SLT which had a 2nd design textured antenna. I changed mine to a color matching Denali antenna. Thanks keep these coming.
Thanks for making this video, especially the good shots of freeing the wire connectors. With your help, 45 minutes of effort, and $51 for a new antenna my GPS is functional again!!
Your welcome. Good job!
Excellent video. Thanks for the clear instruction. I really appreciate the quality of your images --very easy to see what you were doing. I had no trouble changing out my antenna thanks to you.
Thanks. I’m glad you were able to save some money & get this done yourself. Good job.
VERY helpful video. Thank you so much for putting this together, and including the TSB information! My Cadillac dealer wanted $800 to replace the antenna (2016 Escalade ESV). Naturally, I opted to purchase a new one for ~$90 and install myself.
Good job! You’re welcome!
Yo bro this was the best video I've seen on how to fix this,. I wanted to get my GPS an Xm radio back but I had other more important repair. Thanks again
You are very informative and you make it look simple the dealer wants $450.00 to do what you just did. DYI
Now you can save yourself some serious money.
Many thanks! I will use this to get my Dealer to replace the Antenna via my GMC Protection Plan Contract. Much appreciated.
Glad it worked for you.
Thanks a bunch! Now I know why my Nav quit working, mystery solved.
Your welcome. Glad it was helpful.
Thank you this is exactly what I was looking for and the info about the bulletin was super helpful too!
Glad I could help!
Thanks for the great video! I have a 2015 GMC Denali with the exact same issues you described. Planning on trading the truck but if that doesn’t work out, I think I’ll tackle the replacement thanks to you excellent video.
Thanks. Glad you found it helpful.
Thank you man solved my issue 👍🏻
Glad I could help!
Great video, plan to do this on wife’s ‘15 yukon ASAP. 👍🏽
You got this!
Thank you for posting this video.
You’re welcome. I hope it helps.
@@TruckNerd Sir I have another question I have 2015 Tahoe, the N,S,E,W indicator is not working and Onstar is not working no red or green light. The GPS doesn't work the GPS letters have a red line across the icon. Can this be the antenna?
@@jimmyrios6815 yes it can be.
this video saved me from paying 562$
7aMoODaiZER That’s awesome! We all could use a little more money in our pocket.
Just got a quote for $700 to replace mine. Ordered one off of ebay for $90! Thanks for the video!
I replace the antenna in my 14 Sierra Denali and still have a red dash on gps icon and map is crazy
Probably going to have to get it diagnosed then.
Great video detailed!
@@caseydees1391 Thank you. Hopefully it helps.
That paper towel scrub made me cringe
As well as it should. The glass cleaner helps a lot.
What if my onstar has no lights and my gps not working but I still have xm radio working? I have a 2022 Tahoe
Great video, very helpful guidance, tried it on my 2016 Escalade ESV. However I was wondering if you have or know of any other videos for DIY work specific to 16 Escalade ESV's, I will really appreciate that. There are not many out there I noticed. Thank you
Sorry I don’t have a source specifically for your vehicle.
This was very informative , any chance you know the exact location of the onstar module that those items plug into on the 2015 escalade, I need to replace the module I have taken nearly the entire dash down minus the cluster I have the part it was on back order for a year finally have the opportunity to put it in and cannot find the location no video shows for the 2015 escalade onstar module replacement
I believe it’s behind the glove box. Take the glove down & look up.
Impressed! Thank you
Thanks for the kind words.
I replaced mine and OnStar works now but no GPS signal. What would cause that?
Awesome video I really like it I share it I hope that's okay nice job too by the way
Thanks. Share away. I appreciate it.
We changed the antenna on my 2015 chevy tahoe but still no gps or OnStar?? Can u help?
I would start by having your Tahoe checked for codes. Based on the codes stored is where you would need to start.
Great video brother
@@littlej3777 Thank you. Hope it helps.
Do they sell the antenna to match the color of your vehicle or can the cover be swapped around
It’s color matched to the vin number.
@@TruckNerd ok thank you
I’m did replace shark antenna 2013 Cadillac XTS but it still the same not working you have any idea fix problem thank
I don’t have any experience with the XTS. I would suggest having it scanned and go from there.
Dealer was clueless,he wanted to charge 199.99 for a diagnosis test. Thanks
Your welcome. Hope it saves you some money!
Yes they want to charge me the same amount to just check it.. Can you tell me where I can buy the part online and maybe I can have my brother install it.
Yea tried to fix mine 2019 Suburban Premier but I have a fiber or Coax running up to mine. Going to trade it in on a Toyota!!!!! If Gm can’t stand behind their -hit I refuse to buy American 🇺🇸!!!! Yea UAW that was directed to you!!!! 90,000.00 and you can’t stop the thing from a water leak…. That explains the Torque Converter-issue and the DOD issue. I loved Chevy for the last 45 years but today the Music DIED so by by Miss AmERICAN PIE!!!!
Any info on the instar module?
What information do you need?
Mine is not working, and was told it was a bad module. Is this something I can replace on my own?
@@flikofliko1860 You definitely can replace the module yourself, but it will have to programmed at the dealer.
Ok thanks, any videos on replacing or location of module
@@flikofliko1860 I don’t have a video on it yet. Do you have a truck or SUV?
So is that's why my red light is on on my OnStar and my radio is not working is it because of water is inside my antenna
Sounds like it.
So I did these steps and my OnStar light is green but none of the GPS and onstar features are working do I need to register the antenna or something?
There is no set up procedure for the new antenna. If you are outside with a clear view to sky and it still doesn’t work, it will need to be diagnosed.
Rodo, did you ever figure your issue out? I too replaced the antenna and still nothing works.
@@tuxedoblack773 no been having to live with it since the vehicle I had it replaced on is a Volt and it requires the headliner to be dropped to access the the antenna 😭 cost me $300 last time.
Yeah that’s what’s going on in my truck
And now you know how to fix it!
My XM Radio stopped working after installing the navigation update via cd. Dealership is telling me there's water damage to the high frequency antenna and it needs to be replaced. My navigation system works and I don't have a red light on OnStar. Could it be the nav update that caused the problem or do I need to replace the antenna?
Good question. I have seen no gps without the light being red. I would suggest replacing the antenna. It may be just a coincidence that you started having problems right after the update. If your antenna is the old style, I would go ahead & replace it. It will give problems at some point. Is there a GPS symbol with a slash through it?
question is it possible to install onstar module on my 2016 tahoe that doesnt have onstar but has factory navi
The navigation system is in the Human Machine Interface Module (HMI). If your vehicle is equipped with a HMI, I do believe there are some companies out there that can add it. Not 100% sure though. Some base model trucks were not equipped with the HMI module.
Would that be why my dash doesn't say N,E,S,W just CAL?
No that’s a different system. Usually just drive in a couple of tight circles to take care of the calibration.
@@TruckNerd I have no GPS signal. A red slash through the GPS on the radio and my dash says Calibration. Any clue what that could be?
@@CAC-1111 I haven’t run across that yet. Make sure you are parked outdoors with a clear view to the sky.
@@TruckNerd I think my new antenna might be defective. I ordered gm part# 84346801. Thanks for replying
@@CAC-1111 it is possible.
How much did the antenna cost you?
$250
@@TruckNerd thank you
Lately I noticed that my On-star come back online and I had free Sirius Xm. I also noticed that my GPS all of the sudden had my home address programed in it something that I never do. Even after erasing the data and double checking that the entire history was wiped out my address again showed up on my navigation, and I am beginning to be concern since during the last few months I have noticed a particular vehicle following my SUV. I checked for trackers but did not find anything so I am wondering if On-star was hacked if that is even possible. Evidently I want to disable the On-star Feature. Is this something that can be achieve by removing a fuse or do I need to disable the module ? If so is this module located being the CUE or glove box ? Do I need to open the module and disconnect anything inside or just unplug it ? What features will be lost ? It is a 2016 Cadillac Escalade Platinum. Thanks Oli
Unfortunately it’s not as simple as just unplugging the module. Data communication runs through the module. Also there is a back up battery in the module, so removing power may take a while
@@TruckNerd Another you-tuber showed how to unplug the module inside. If I understood this correctly there are two boards and a connector in between and if this connector is removed it kills gps and xm essentially killing the tracking feature. So if I could know where the module is located that would be great. I hate to have to take half of the vehicle apart looking for it. Another idea I had was to disconnect the fin on the roof. Will this not prevent the module from transmitting or receiving any signals essentially rendering this feature useless ?
@@OLIVIERIKRIS The module is connected behind the glovebox. Take the glovebox out & look up.
What's the part number for this GPS antenna in black from ACDelco?
You need to call your dealer & give them your vin number. They can give you the correct information.
Can put link of where you bought the antenna?
I purchased it from the dealer. There are many different part numbers depending on the color of the vehicle.
Sir r u in NYC please let know
MY FAMILY no sir. Southeast for me.
2022 Silverado ltz
Okay that’s a different body style than what’s listed. It may be referred to as a communication interface module or telematic control module. It’s located above the gas pedal.
Quick question. How does the shark fin antenna connect to the radio? Is it a separate module or is it just one that goes straight into the stereo unit?
It goes in through a splitter then to the on star and HMI and one lead for XM goes to the radio.
@@TruckNerd do you know if the factory setup would fit into an aftermarket stereo?
@@rohastechreviews I’ve never thought about that. Most aftermarket radios come with their own GPS/ XM antenna, so no need to use the factory one. I guess someone should make an adapter for the FM/AM antenna.
@@TruckNerd I'm curious if it would fit. I got an aftermarket stereo installed and they said that they couldn't connect the old one in and then tried to sell me their own. Dont want to get scammed. I know maestro idatalink has them but they don't for my truck just yet
So youre telling me after spending 114K on a vehicle, i've got to put silicone to prevent this from happening again? BRUH
Unfortunately so.
@@TruckNerd Sadness :(. Yeah I tried to do that CUE 60s reset and the gps still doesn’t work. Wiggled the Antenna and it was loose. Where can I get an Antenna?
@@Edokun90 the dealer will need to order it. It’s color matched to your Escalade.
@@TruckNerd thanks man! You’ve been great help!! ❤️
I did a atenna replacement on my 2015 Chevy Silverado 2500hd ltz and it still doesn’t work. I changed the antenna and it still says no gps
You probably need to get it scanned for codes, then go from there.
@@TruckNerd how do I get it scanned?
@@MarkyMark2003 you will need to take it to someone with a scanner capable of scanning all modules. Your local dealership will have this as well as most aftermarket shops.
Great video!
@@caseydees1391 Thank you.
