Please first try to update to firmware 1.4.0 and set the USB mode to "Default". If that doesn't help, follow these instructions:

  • Go into Settings and select Apps and Notifications (see all apps)
  • Select Android Auto
  • Select Advanced
  • Scroll all the way to the bottom and select Additional settings in the app (this will open the AA settings)
  • Scroll all the way to the bottom to the Version number
  • Tap 10 times until it says you have unlocked Developer settings
  • Now you can select Developer settings from menu by clicking the three dots in the top right of the screen.
  • Enable "Request video focus on start"
