I have my 21 setup so that the Ford Nav is always on the main screen and Apple Music via carplay is alwasy on the side. It always appears this way when I turn my truck on.
If I use my phone for apple maps, as mentioned, the wireless charger does not provide enough voltage so I use a cord plugged into the center console compartment. The phone sits in the horizontal phone slot since I use the Carplay screen as my phone interface. The built-in cordless charger seems to work fine if I just stream music that is downloaded on my phone to the Ford stereo system
