Have you ever tried to navigate the S&T interface while driving?
How come no one has a plugin for Streets and Trips 2008? It seems like it is an affordable solution. Is there something wrong with S&T 2008?
Why the substantial price difference between S&T and Other Nav software?
I run MapPoint 2006 in the car along side of Destinator. I MUCH prefer MapPoint in terms of cosmetics, but it's a real PITA to deal with.
CF's nav system has a starter module for MapPoint, but it's not enough to really use. Maybe someone will pick it up and make it real...
