I just discovered this today while I was playing around in the car. Using the 'APP' button and the thumbwheel, you can quickly access your AM presets, FM presets, XM presets, Phone speed dials, and song titles on a connected USB stick among other things. All with the info right between the tach and the speedometer. You don't have to look at the video screen at all!

This is very fast and very cool. I haven't read anything about this, so sorry if this is something everyone else has already figured out.

 

 

For HUD equipped, it can display that info on the HUD. I need to play with that more
