[Android Auto General] nggrant:
I've had exactly the same problem with Moto G6 (4GB RAM/64GB Flash) and XAV-AX3005DB.

Tried upgrading XAV firmware from 1.10 to 1.11, no-fix.

Upgraded Moto G6 from Android 8.0 to 9.0, no-fix.

Tried various "usual" fixes like developer mode, USB debugging - still no-fix.

There is a flying USB lead out of the back of the Sony. I've got an extension USB cable plugged into this. Replacing or getting rid of the extension cable is the only thing I haven't got round to trying yet (I need to take the fascia back off to do this).

I've got a Logcat file out of the G6 that shows Android Auto crashing. I'll include it below, but I'm not sure it'll be of any use. From reading the above thread, it feels it's more a problem with the Sony than the Moto.
