I, too have issues with the NAV system. I returned from West Virginia to Indiana a week ago, and selected the shortest route. The route was pretty similar to my Oncourse Navigator on my Dell Axim. But when I returned yesterday, I tried to get the same route (it seemed to be faster than the OCN route) but each time I tried to reselect it, it was different. And I was on the same road each time. I could not duplicate the route.

Wouldn't it be nice if you could reprogram the NAV system with say . . . OCN, or Tom-Tom . . . and keep all the other features of the unit?
