Hello Prepared waypoints and have file in gpx format. Copied it under Garmin/gpx directory. Map is under Garmin directory. When I open the unit, I want to go to my route but unit shows a former route only, not my loaded one. I have formatted micro SD and copied the map and gpx file again. Is there amemory on my Montana unit which keeps all waypoints and tracks and routes? How can I reach and erase it? Thanks
