A month or so ago I stumbled across a thread talking about this but can't find it now. I am taking a three week trip and am taking a small Samsung Chromebook which can't have programs loaded onto it. I want to use an online program to create a route(s) on the fly. I could then connect via USB to my Garmin 550 to load the gpx with the online program or at least I think I can. I have tried this with Google maps and never been able create a route much less convert to gpx or upload. Anyone know of an online source for what I want to do?
