Afaik, on pretty much every modern car the single main antenna unit (usually the shark fin on the roof) handles cellular and GPS (Rx only) and radio (AM/FM, and often also weather/traffic, Rx only).
So you'll lose the other things if you put it in a Faraday cage.
A cage is a bad way to do it anyway. It's easier to disconnect the cable between the antenna & the telematics module (which has the SIM and control electronics in it). Or disconnect the power to the telematics module. Etc. Depending on the wiring harness style and design of the car's electronics, that may also let you disconnect just the cellular antenna while leaving the GPS/radio antennas connected.
In the future we might see those components getting integrated together... But you can always physically destroy/remove the antenna.

- the_pwner224 4y agoThat's already happening :) If you have an automatic toll transponder (ez-pasz, etc.), those things are read very frequently even when you're not going through a toll meter. There's info on this online. TPMS sensors also transmit a serial number. I wouldn't put it past the NSA to have sensors embedded in certain roads to track that. And of course, dragnet automatic license plate scanning / tracking is already ubiquitous and there's really not anything you can do about it. Use a bicycle instead, I guess...
- GekkePrutser 4y agoMy Irish one wasn't. It beeps when it's being read and it was only read at toll ports.
- lcnPylGDnU4H9OF 4y agoI mean, what if it only beeps when it's being read and the reader doesn't mind you knowing about it? Not that it's necessarily happening but I don't see how that would be impossible.
