> You can disable the over-the-air capabilities But how? You may be able to opt-out in software, but that's not trustworthy IMHO. There's no simple hardware disconnect, and I'm sure it's different in every model. In my friend's car (a Subaru), there's a telematics module under the head unit, but you have to disassemble the dash to get to it (i.e. do a pretty significant amount of work). IMHO, telematics should always be implemented as a separate module with a separate fuse, so you can just pull a fuse to disable it. > but if the dealers can download over diagnostic ports when you bring in for servicing, it's worse. Someone sells a lock to cover the ODB-II port of a vehicle. I got one years ago, but unfortunately it didn't work very well and could be trivially pulled (or bumped) off. The port in my car is pretty close to my knee.
