I can't speak for the more modern cars, but my 2019 corolla had a cell phone connection which could be cut by pulling a single fuse. Idunno if it's a universal name, but it was called the DCM module. The emergency button in the roof was wired through it, and so was one of the right speakers and the built-in microphone. None of them work with the fuse removed. I'll route the speaker and mic wires around it at some point by going through the glove box, but it hasn't been a priority for me.

I'm happy i did that too. Apparently toyota is still leaking the location history of a bunch of their cars and i'd hate to see that get abused.
