I have a mag gps 315 and trying easygps I could upload all my waypoints to computer but not download to the gps. i tried everything listed in the easy gps but still get an error 23 msg.
I have an old (7 years) garmin that works great and I bought a Magellan for my wife but it is 50 ft or beter off in any direction. can it be adjusted for accuratcy?
