I’ve been playing with this and I think I like it. Haven’t created many routes yet but did run into trouble trying to undo the last point I added. Unless there is a way to fix that that could be a deal breaker. I was able to get someone elses route to my GPS as a route (through using GPSTracker) which was cool. I love planning my routes on gmaps but hate having to reproduce the route on the archaic Garmin software.
Need to play with this some more but so far it looks promising.
