Ya a lot will have gps built in but as others have said, the map will be static (whatever version was put in when built). Unless you have it updated by connecting it or buying an updated USB or whatever is required for your car
So ya it’s likely yours has both a gps antenna and navigation built in.
Oh ya for sure it has a sim.
If it were my daily driver I’d dig in, find the antenna and shunt it to ground so it could not communicate
My wife is already not fully onboard with my need for privacy from these companies so I won regarding not activating the car but not sure she’d let me start pulling panels to find and kill the antenna.
