If you use the mapping & record keeping features of the 500, you need to go to the Trimble website and download Trimble EZ-View & EZ-Guide Name Tool. Both are free downloads.

The CFG files store field, farm, equipment, operators, etc. I find the Name tool to be a bit nicer for setting up that part & looking at & changing info.

When you off load the coverage mapping from the 500, EZ-View does a pretty good job of viewing those records, once you get it figured out.
