My unit came with a MapSource Trip & Waypoint Manager CD, but I can't get it to load. I think it is a Windows Vista issue, the unit is an older one that has been on the shelf a while. I tried to load an update from Garmin, but since I don't have it on the PC yet it won't let me.  >:(

Have you tried the steps outlined on the GPS File Depot site for loading MapSource? My old MapSource CD that came with the GPS didn't work for me either. But, I was able to install MapSource following the websites instructions on 64-bit Vista without any issues.
