map and music quirk

here's the quirk: You go from CD to radio, or whatever, then you lose the ability to scroll various map scales. You have to redo the map thing again.
Does anyone ever notice this? Not a big deal, but it seems I'm always scrolling through the map to the "vehicle position" setting to be able to change scales.
\(I guess this should be our biggest problem with these cars...

In any case, once you start navigation, the map display would change immediately to full screen. I'm not sure if you go back and forth from the navi display to the radio and back to navi with the specific buttons if the map remains in full screen of if you have to select to full screen first. The point anyway is that navigation should be used in the full screen mode and then you can very conveniently scale the display (I never go the menu route you mention, if I got it right).
