The route you save isn't actually a route. It is a set of stops. Different routing algorithms can make two different programs show different roads to get from point A to point B.
I haven't worked with the GS Planner, but I add extra waypoints at intersections, towns, etc to get my Rand & Garmin GPS units to use the route I want.
Exactly. Trip planning, either on a GPS itself or on a computer/tablet, is just a series of waypoints. Every device then has its own logic for connecting the waypoints. Use more waypoints to assure you go the exact route you want. In the Garmin world, their BaseCamp software calls these "shaping points" where you don't actually stop.
For instance, to go around big cities to avoid heavy rush hour traffic, I usually have to use several "shaping points."
