I'm curious on this too. First "mod" I'm gonna do when I pick this car up
Do you navigation? Is that located on the driver or passenger side??I disconnected the telematics connector at the in dash module
I found the telematics communication unit (TCU) location and its antenna. The telematics and GPS antennas share the same connection to the TCU. You can find this diagram on page 433 of this section of the service manual.Do you navigation? Is that located on the driver or passenger side??
thanks,

The AV unit must be completely removed from the dashboard to remove the TCU itself. They connect to each other by USB. The mounting method is the same for cars both with and without navigation (page 343).

This is the routing of the TCU antenna cable to the TCU, found on page 438 of the same section. The plug to the TCU may be reachable by removing the glove box and the surrounding trim piece. Each half of the antenna is attached to the underside of the dashboard by one screw.

Additional removal instructions follow. The center air vents and lower trim around the AV unit must be removed first, as detailed in this section.

I don't have access to my car right now, so I can't test these procedures myself, but I hope someone else in this thread may find this useful.
wait ... so if you unplug the TCU antenna.... the car wont start?if you shut off you have to do it everytime you restart car.
No no was speaking of shutting on menu on start - sorry for panicking youwait ... so if you unplug the TCU antenna.... the car wont start?
That kind of information is recorded in the PCM, which is not the TCUSpoke with a guy at work today that worked at a local GM dealership. A guy had his manual Camaro towed in with a grenaded engine. ‘Was driving and all of a sudden, ka-blammo.’ He said they got into the “flight recorder” and although it didn’t show what gear he was in, he was cruising at 87 (~3200 rpm) and it immediately went to WOT, 9600 rpm, and boom.
He was denied warranty service.
All of you may already know, but if a car can monitor something it can record it, and most if not all new cars record. A little different than constant monitoring, but still intrusive.
Sounds like he money shifted it, you can get that out of a Snap On ZEUS scanner also at minimum it can give you a snapshotSpoke with a guy at work today that worked at a local GM dealership.

Yeah, guessing 6th to 3rd. Although he denied it. Then THEYSounds like he money shifted it…
If anyone has done this on there Z, sharing the location of said connector would be much appreciated.

Having attempted this today, I can confirm that it's not possible to unplug the TCU or its antenna without at least partially removing the head unit. By going through the passenger side after removing the glovebox surround, I was able to feel the antenna connector on the back of the TCU. There's not enough room behind the TCU to release the plug and back it out. The plug is very nearly in the middle TCU, so you won't have much better access by going through the driver side either.I dont plan to remove.... just disable it by unplugging
There's a way to turn off vehicle data transmission that keeps it off even if you restart the car. From the main menu:Ok, I am pushing my dealer to get this done - if you shut off you have to do it everytime you restart car.
Agree, but I still don't like even this. I really wish the car would just turn on and jump right to operating mode with no legalese screen involved. I feel like I'm signing a contract every time I drive.The screen will display "Vehicle Data Transmission is LIMITED" every time the car turns on. Given the effort needed to take apart the dash to free the head unit without damage, I think this might be our best bet for the time being.
