I don’t know if this is an android auto problem, or an android 14 (crdroid 10) problem. Wired usb connection. Have tried different cables with same effect. I did not have this problem before (Android 13). My phone has AA 10.9.634644.

If the phone is locked when connecting to the car, I get a connect/disconnect loop. This continues until I unlock the phone, and then things are fine after a few seconds, and I can then lock the phone again.

If I connect to the car with the phone unlocked until AA connects, and then lock the phone, everything is fine.

I have android auto configured to connect with the phone locked, and have disabled USB debugging.
