With Garmin's topos and others like the OSM-based ones I linked earlier you can set two waypoints 20 miles away and the GPS can find a path that gets between them. To make a route that lets the GPS give directions I need a whole lot of waypoints on the gpsfiledepot topos and it would be directly routing between them. ![]() That's OK, sometimes tracks I've done or downloaded followed different trails that might not exist anyway, but I know waypoints are current. If I'm following an existing track I'll go and add periodic waypoints to help but it's no guarantee that my eTrex will necessarily route the same. I can tell if I'm not on it but the GPS (I have an eTrex 20x) doesn't actively tell me left or right and give upcoming intersection warnings with them. I'm not talking about a track, which isn't dynamic. The topo maps on gpsfiledepot (at least the one I got for Colorado) show roads and trails but they aren't recognized routable features. Click to expand.I mean a route in that it creates a path between two waypoints that isn't a straight line and is constrained to an actual existing feature.
