I have used it, but it is difficult.
To get an accurate trip, I have to zoom into nearly street level, mark as a waypoint, then expand the map and go to the next part of the route I wamt, zoom back in, drop another waypoint...... a pain, but it can work.
If you don't check the options for the types of roads you want to travel on, the Ride Planner will take the settings you have and map with them.
If tou try to do long stretches of road between waypoints, you may get loop backs or false exits. that's why I zoom in.
As far as the GPS, I don't have any problem with the ride planner identifying my gps. I use the manual mode alot.
Best thing is to play with it until you get a system that works for you.
