I noticed when I started using Basecamp, my gps unit has double waypoints in it, now. I extracted all data to basecamp, then deleted all the waypoints in my GPS. Then I sent all the data from basecamp back to my GPS, but only got some of the waypoints back...maybe 25% of them.I can see all the points in basecamp, but they're not transferring back to my GPS. Any suggestions?
Also, when I plug in my GPS to the computer, the "All Data" folder in Basecamp which shows whats on my GPS now, shows all the points I put into it...They just don't show up on my GPS.
When you list waypoints, only the ones nearest you are shown. Is that perhaps the problem? Try searching for a known waypoint and see if you can find it that way. Otherwise, not really sure. You might visit Garmin's Basecamp support forum here for help. We are primarily focused on creating maps on this site, not on using Basecamp. :)
