Does anyone know if the touchscreen has multitouch capability? Even if it doesn't have it now, it would be super-cool to add in a firmware/software update (if the hardware supports it, which I assume it does). As I was driving home from work today I thought how cool it would be to have some customizable multi-touch functionality. Notwithstanding the controls on the steering wheel, it would be super convenient to make other adjustments using the touchscreen and multi-touch, meaning you wouldn't have to look at the screen at all. For instance, a two-finger swipe up or down to adjust the air suspension...a two finger swipe left or right to adjust volume...a five-finger pinch to turn off the climate control, etc... Edit: These gestures would work from any screen...so it's fast and requires no visual attention.
