    Thanks for the teardown. it reminds me of why I became an engineer. As a kid I used to tear down everything I could find! With battery backup, this telemetry module should probably scare car thieves. and they threw it away.

    Those two items found together indicate that someone didn't want a vehicle tracked. Removing the telematics module alone would have complied that however. Now the radio won't work either. 😊

      Yeah I'm not sure why both were removed. They could have left the shark-fin antenna on the car so it would not have a hole in the roof. All that was needed was to unplug the telematics unit from power and remove the internal battery.

    Did you have a Freudian slip? You stated you found it but in the video when you found battery you said it might have been tracking you.

    Just a guess but, the fin is probably the cell phone/wifi antenna, the square, flat, horizontal antenna is for the GPS and the odd, curly antenna is for the am/fm radio.

    how do you remove a telematic device from a 2023 dodge challenger and where is it?

    • @devhackmod
      @devhackmod  3 หลายเดือนก่อน

      If you see an external antenna, follow the cable for it and see where it goes. I have no idea where these things are located in various cars (it's probably hidden so it's harder to thieves to get at), but you will find a module connected to a power source (vehicle battery). Please remove at your own risk, I don't know how critical it is to the functioning of the car or what features will get disabled if you do!

    Finding both the antenna and telematics module together, in a field, showing signs of being hastily removed... My money's on theft.

    • @devhackmod

      I don't get it, why not just remove the battery from the unit and unplug it from the system? Without power it can't operate. Why rip it off the car completely and leave an obvious defect in the roof? By the way, I found another one not long after in a different area (just the telematics unit) and will be doing another proper teardown of it as well (stay tuned!).

      @@devhackmod Speed. It takes less time to unscrew, snip, and toss to keep the car from being tracked. Besides, they can't sell a whole car with a VIN reported stolen so it'll end up at a chop shop and sold for parts. The missing telematics and hole in the roof wouldn't be an issue at that point because neither could be reused.

    Thanks for the teardown. These telematic units are known to become unstable and not work right when the transmission is turned off. These units are used for EV cars to report charging state and activity. Seeing the teardown shows the internal battery and probably the reason these units are becoming unstable.

    • @devhackmod
      @devhackmod  3 หลายเดือนก่อน

      It doesn't explain why someone would tear off the antenna when only the module is the problem. You can change the module or battery (if faulty) and leave the antenna on the roof of the car. I'm sure it can be used with another module. Seems odd when you could just unplug the module and remove it's power. The antenna won't do anything by itself.

      ​@@devhackmod​@devhackmod it prevents data transmission which is the point. These antennas predate EV's with gm starting to use them back in the early 2000s with the adoption of onstar. What started out as a service for customers who opted in has grown into an industry based around harvesting a drivers data. Today these things record how you drive, where you drive, the exact things you did in the moments preceding an accident. The biggest customers for this data are insurance companies which have been known to deny compensation even if a driver was found legally not at fault. The insurance provider will look at the data from these little black boxes and base their determination on that. Newer vehicles can and do record everything from the above mentioned to conversations and the like, just as your phone does. So someone who doesn't know what the telematics unit is, where it's located etc might just resort to ripping the antenna off to prevent that data from being transmitted. Oh and many insurance companies today require these units to be functional in order for their coverage to be valid

      @devhackmod  10 หลายเดือนก่อน

      From what I see online, the 2022 and 2021 models have it under the infotainment control unit. So I would imagine that for 2023 it is likely in there as well. That means it isn't so easy to steal it or disable it maybe?

    It spies on you and how you drive. Reports to Toyota for "diagnostic purposes" and they sell it to insurance companies and they raise your rates due to the driving habits the DCM module keeps track of and transmits.

    • @devhackmod
      @devhackmod  5 หลายเดือนก่อน

      While I'm sure that is technically possible, I'm not sure your car manufacturer would give this out to 3rd parties unless they record all the data and make it available for purchase by insurance companies (and others) who want to look up their policy-holder's driving habits. But if that was the case, insurance companies wouldn't be asking people to install apps on their phone to track driving or giving them monitoring devices to plug into the ODB2 port to receive discounts. Either way, it's scary how much data they gather and whether it can be abused to track people unknowingly by law enforcement, government and others (without proper legal processes).

    • @devhackmod
      @devhackmod  7 หลายเดือนก่อน

      Why deface the top of the car when you can just remove the battery from the unit? Surely that would stop any telematics transmission to cellular towers? Or is it just that they need to do it fast and just don't care? The shark-fin is the antenna but the actual unit can be opened and battery removed fairly quickly too. Why remove the antenna and screw up the top of the car if they already removed the telematics unit?

      Yes I gather, but why remove it instead of just disconnecting the battery from the module if you already know where it is? They chucked the module and it has a battery so just unplug it and that's it, rather than leave a hole in your roof!
