Both of which require Bluetooth pairing (or at least auto-pair without asking you if I recall correctly) which allows the head unit to siphon data!

You can disable Sync Contacts (PBAP) and Notify Messages (MAP), and then the Bluetooth head unit won't download your contacts or messages.

Unless the head unit refuses to operate unless you share those

Apple CarPlay works over my USB-C cable, at least in my 2018 Subaru Crosstrek on an iPhone 15. No Bluetooth required I am fairly certain. I also have to unlock the device every so often with my Face ID -- unsure what triggers this as it is not 100% of the time.

My car also uses wired Android Auto, but somehow after I set it up the day I drove it home, my phone automatically connected to it via Bluetooth. I recall something similar when a friend plugged in their iPhone but I’m not sure.

I always connect to CarPlay with a wire, and have never connected with bluetoooth. It has not auto paired Bluetooth either with iPhones.

I have not used Android Auto, but if it does auto pair Bluetooth, that would be a shame. I thought the whole point was that the car just provides a screen your phone can extend a display to, and no data ever leaves.

Android Auto can do both wired and wireless. Wired in fact is the only option on cars more than a few years old.

Yes, but the question is does it auto pair (without permission from the user).
