The car I bought last week is a Toyota. Upon getting home I immediately followed the instructions on the sticker near the center console to hit the "SOS" button and request deactivation of their telematics services. The rep on the phone mentioned something about how she needed to create an account for me or something before she was able to process the opt-out and then, I guess, did so. Of course I have no idea what this opt-out does. The skeptical part of me suspects that the system still collects and transmits my location and such, but then they simply don't trivially attach that telemetry to my account. I'm also going to try pulling the DCM fuse that's supposed to cut the cut the gateway/telematics antenna. I also plan to wrap the transmitter in a Faraday cage.
