I have been using MapSource for many years with my Garmin 60cx. I sit in my computer room and make a track in the woods and then go see what I can find when I ride the track. I have over 60 tracks mostly in northern California and some in Baja. So I decided to upgrade from my 60cx to a Garmin Montana and downloaded BaseCamp. Now I wanted to import my tracks from MapSource to BaseCamp. BaseCamp imports the file I requested to be imported along with waypoints from other files saved on my computer (not tracks just waypoints) and puts them in the correct location on the map area they occupy in other tracks. Then I need to go and delete the incorrect waypoints that were imported from the track I just imported. I think it is something to do with this MY Collection BS. When you open My Collection every track and waypoint you either imported or created is in there. Sure seem to me that a better system could have been developed. When I called Garmin for some explanation for why this was happening I was told I was the first person to have this problem. Well being in the Motorcycle off road community for many years, being told your the first person to have this problem means, ya we are working on the problem. That's my 2 cents!
