So for those with the Lifetime Maps, if they are doing away with Mapsource, what are they going to offer as a replacement?
Regarding route changing, I usually use the one tool to make the route, clicking on Point A then the final destination. Then I go back and double-click on the route with the arrow, and pull the route where I want it to go, starting close to Point A. Keep doing this near where there looks to be forks in the road, and with enough of these waypoints, it'll stick. You just have to make sure you don't leave any optional rerouting available and it works fine. The only problem is, you get reminded of approaching way points, so place then at turns, and they blend in.
My .02 fwiw, but I'm certainly no expert!
