My car has in built (TomTom) sat nav too with a nice wide-screen display. The tom tom maps make full use of the screen and very legible. Android auto gets forced into this like 4:3 resolution in the middle of the screen which sucks and I can't find a way to fix it, even after looking in developer settings. People have said it's the car manufacturers fault, I really don't understand why it has to be this way though
