To be specific, it’s not the GPS receiver, it’s the fact that the car may be communicating via cell network or satellite, right?
Right, but most modern cars have that communication built in, because they use it to update firmware remotely. You can’t turn it off even if you wanted to. Many car companies justify it by saying it is needed to give your location to emergency services if you use their alert button.
Idk about other brands but with Mazda you can call and get them to deactivate your car’s sim. IIRC in Subarus you can just physically unplug the communication unit.
