Hello
I have a garmin legend. Very nice unit and its able to load maps into it. I've had it for several years. Two of my brothers and my son also have the same model. Theylike theres as well. I also do a lot of bicycling to stayin shape and with an optional handlebar attachment it works great on the bike as well, logging speed, distance traveled and such. Also have a bracket for mounting in my hunting truck.
No, there are no fees required to use the unit. One brother is in the Air Force and he uses his in Germany.
