v4.0 gave us the ability to set the right scroll wheel to a whole bunch of different options - sunroof position, temperature, fan speed, etc. I think they missed a biggie now after having taken a long road trip: - Map/Nav zoom level. I find I constantly need to zoom out to check overall progress, zoom in to find details. And the map zoom buttons are WAY over on the right side of the display, a bit of a stretch. (Yes, I know you can use mult-touch pinch/stretch). But having a scroll wheel option for map zoom would be fantastic. Lexus has a similar shortcut button for map zoom in/out on the joystick pointing device mount, and it's invaluable. Others? - audio favorites scroll. The left-side "next" and "previous" are a pain if you have tons of favorites (I have at least 50 between XM stations, TuneIn stations & programs, etc.). any others?
