GoKawiilGoogle details Android Auto options for layout, wallpaper and map modes
Android Auto includes settings that let drivers swap the position of the map and media player, mirror their phone's wallpaper onto the car display, force day or night mode on maps, and disable automatic media playback at startup. Wallpaper mirroring must be enabled from the car's Android Auto settings rather than the phone, via a toggle for 'Use Phone's Wallpaper'.
