We've run into a real head scratcher...when we try to download a new cache into our GPSmap 60C, the message "waypoint file is full" comes up. The only way we can download a new waypoint, is to manually delete an old one. What's up with this? Can't find any way to clean out the waypoint / found geocache file en mass...Would like to clean out these files regularly to avoid this problem. As an alternative, I guess we could "reset" the unit?? could use some help on this please Thanks!!!
