I plan on riding the Mid Atlantic BDR in September and have been reading for the last week on this sight and others about how to load the map into my GPS. My problem is that I have a car GPS (Garmin Drive 50LM). I have never used the GPS for this type of adventure ride. I loaded the tracks from the MABDR website into Basecamp but from what I can tell, my GPS will not recognize tracks. Am I wasting my time trying to do this with my current GPS? When I have the GPS plugged into the computer and Basecamp open, the route shows up fine on the maps that are loaded in the GPS. Help please.
