I recently purchased A Garmin Oregon 450. I transferred data from my Etrex to it. That worked great. I started using Mapsource to manage the data. Then I had trouble saving waypoints back to my GPS. Now I am trying Basecamp. I got all my points from Mapsource to Basecamp, then successfully into my GPS. I noticed later, that some points in my GPS were duplicated. I had some more data to edit. Then I reset my GPS to clear out all the data, trying to get rid of all the duplicate waypoints. I sent all the data from Basecamp to my device, but when I turn on the GPS, I get only a fraction of the waypoints. I tried it again, and the same results. The folder I made in Basecamp has all the data I want, but it’s not getting into my GPS correctly. When I then hook up my GPS, the “All Data” folder from my device has all the data I put into the GPS…so it seems it’s in the GPS, I just can’t find it. Any suggestions?
Otherwise, I’ve found Basecamp to be very similar to Mapsource and I really like being able to edit data.
