Modern cars are computers on wheels that send home nonstop telemetry about you. In this post I remove my 2024 RAV4 Hybrid's modem and GPS to prevent that :)
There are a number of writups online, but basically you disconnect the antennas at the head unit, and replace with these. Without them there is no resistance so the system knows things are wrong (and damage can be caused), while these fool the system into thinking there is no signal.
How does it work? Where do you put these things?
