It is (to me at least) non-intuitive navigating the menus while using the head unit in landscape mode. Particularly the up/down buttons pointing left/right seem backward in the interface (i.e. the down button is above the up button in landscape mode, and they are separated by the select button). I can't seem to get my brain to push the correct buttons when I have the unit installed in landscape. I wonder if there may be a way to rework the menus in that mode through firmware or something that makes it easier to use.
