I find it incredibly frustrating that road closures are impossible to report in AA mode and thus rerouting around a closure requires unplugging my phone and then usually backtracking so I can actually mark the route as closed because it won't let me mark as closed behind me.

If I could just use the normal UI on my phone at the same time in the same way Google Maps does it, that'd solve that problem.

It is a must especially for the older car models without touchscreen

I have unplugged the phone from the car many times to search for a place and reconnect. Especially when I search for a place I do not have in my bookmarks.

Google Maps can be used in both places as complementary information (turns) and any configuration.

It's usually easier to search on your phone instead of using your car's Android Auto screen.

When I drive with the family for holidays and there is need to search for poi's and add stops on the go... it is definitively an added safety if the front passenger can do these from the phone while the driver focuses on the road.

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.
