Hi Catymag, I woul like to install several maps (Mapsource) om my PC, before transfering (parts of) maps to the GPS. The C-partition of my HD does not have so much free space, but my H-partition has plenty of space. When installing maps, the installer aks where to install the map. Even when I choose the H-partition, maps will be installed in C:\Documents and settings\All users\Application data\Garmin\maps. How can I get the installed maps on the H-partition? Thanks for your help.
