Is there a way to display a track in a DriveSmart GPS? I can upload Routes, but as there are no mapped roads in the area, Drivesmart only displays a path using roads in its maps. The roads Im on are not in the Garmin map database. All I need to do is display the track uploaded as a .gpx from Basecamp to the Drivesmart and no need for directions. Just to display it correctly per the .gpx. Thanks..
