At the same time, a navigation option on a new car is generally in the $2000 range. I doubt many people would want to pay $2000 for a radio upgrade. We might, but we couldn't keep the empeg afloat as is.

Well, I'm assuming the camelot/empeg will work in conjunction with nav system. The only real experience i've got with them comes from a GS lexus, and the nav display handles just about everything in the car, including climate control, maintenance indicators, and music. Empeg functionality is going to be just one of the many features of the $2,000-4,000 nav option.
