[Quick Question about Android Auto Hi-Res.]

Hi! I know Android Auto a fair bit, so allow me to explain some things.

Android Auto does output audio via USB when connected in wired mode and via Wi-Fi when connected Wirelessly.

Bluetooth is not used for media streams in Android Auto. It's used for routing phone calls to the car and for comunicating WiFi SSID + Encryption key to the phone for wireless connection. 

Android Auto has a AAC Encoder which outputs in MP4A-LATM at 512000 bits per second. Basically Android Auto takes the whole audio processing and whatever it receives from a media stream it outputs it to the car with its encoding solution.
