I have the 12" screen. IMO, it looks very cool but from a functional standpoint it's a flop. Maybe I'm missing something, but I think I would me much happier with the 8.4" and hard buttons. None of the cameras show full screen. The only app that does work full screen that I know of is the NAV and I usually use Waze for that. Using the touch screen is too much of a distraction for adjusting the climate control. Hard buttons would be so much easier and less distracting.
