Default Contour ShuttleXpress controller hands-free

Hello everyone, This is my first post, but I've been lurking for months.

I have a nook color with ics. I want to use my nook in my car to display Navigation, Music, etc. I can't see myself using it primarily with tough control for safety reasons. While riding with my brother in the Mercades, I noticed he has a nice rotary encoder/jog control to operate the navigation and want to do something similar with the nook.

Contour ShuttleXpress

Anyone know of how this might work? I see this thread, but could not post any questions for I am a noob.....
