Sage Rat 5

Can you use the same GPS location for two different waymarks. Example A waymark Oregon history and also A waymark Lewis and Clark trail marker. Same location. If so how do you post them.

I plug the unit into my computers usb port it comes on with a ICON that looks like a USB port on the GPS screen. I can do nothing with it when plugged in. The computer recognizes it and shows the drive and basic information. When I try to down load information from mapsource or easy gps I get a error message that says comand could not be completed.
