I have loaded some Topo 24k maps, some CN maps and the entire world map set. When I go to map setup and try to choose a specific map set, all I see is one map set listed is "June 2008".
The way I understand it, is you have to load all the maps you want at one time because previous maps sets are erased each time. So how do I choose CN, Topo etc.
I like the Garmin, but IMHO the interface and PC software is less than intuitive.
