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).
