That is a very reasonable level of diligence, but I don't think it's right to characterize further skepticism as "schizo" -- lets imagine the car has a separate entertainment system or sirusxm radio (perhaps not the case for yours)-- in that case it might have an entirely separate telematics function reporting back to a different corporate master. Because of how cars are built there are many places where subsystems are effectively duplicated. Sirus performing telematics in addition to the manufactures hardware isn't a hypothetical example.

More fair to say that you satisfied your level of concern. But it's entirely not schizo for someone to be concerned that there was more than one tracking vector, especially given that manufactures already active inhibit efforts to disable tracking and ordinary practices of the automotive industry.

Or, in other words, please don't privacy shame people. If you felt your approach was sufficient-- awesome! Better to be nothing like the people who were others names online for asking about disabling telematics at all, only to be all shocked pikachu when their insurer jacked their rates later based on their driving activity. :P
