I was given a large number of waypoints, each saved as an individual .gpx file. I'm unable to open any of them in Basecamp - always get a "is not a valid GPX file and could not be opened." message. However, they will open in Google Earth.
I opened one of the files with TextEdit, and it appears that they were edited and saved with Route Buddy 1.1. I'm guessing that Route Buddy saved them in a format not recognized by Basecamp (but being a newbie, that's just a guess).
Any help would be most appreciated.
