f. no touchscreen. I am using a monitor, mouse, and keyboard.
2. Android Auto:

3. Steps to reproduce

f. Setup the audio input and output to be the UGREEN usb external sound card.
g. Connect my phone bluetooth to RPi4's bluetooth dongle.
h. Plug my phone to RPi4 to start AA, and received "Unable to open MTP device '001,005'" and a black screen.
i. Unplug and setup OAP wifi hotspot.
j. Enable wireless AA on both OAP and phone.
k. Connect my phone to OAP hotspot.
l. Select Wifi AA, and got a black screen.
m. Audio from phone to RPi4 to speakers works, but nothing on screen.
