No, you're not missing anything.

When I use Mapsource to load routes into Garmin GPS units, I click a start point and then click at verious points along the route and the program connects the points following the streets on the map. That is what I can't seem to get to happen, the track option connects the dots but goes from A to B to C in a straight line, not following the streets. Either that isn't an option or I'm doing something wrong. The other piece of the puzzle is getting this to display as an overlay in UI-View which uses PMap 9 for the maps.
