Allow viewing on mobile while connected to android auto
When my phone is connected to Android Auto, viewing the app on the phone is disabled but not all features are enabled on the car display which are often needed. I cannot change my vehicle type (car/motorcycle), I cannot share my ride, if I am not currently navigated I cannot change alert settings.

Often time, I need to go from point A - B - C.
When I reach point B, I would unplug my phone and set to point C and re-plug. It is kinda tedious when doing this multiple times a day. -

I only use Android Auto and too many functions are missing such as being able to enable/disable toll roads.
When I used Carplay the iphone acted as a second screen with all the turn by turn information which was pretty neat. Definitely need more functionality that the phone provides.
