Hi all. Ive been watching with interest some of the excellent digital cartography that the members on here can turn out using "memory maps" so I downloaded the program freeware version and set of files for eastern victoria. However Im having trouble getting the base map to zoom in close enough to get enough detail & i am also having difficulty with the overlay / transparencys . I was hoping that it would connect to my magellan 610 gps as well but I cant get that to happen atm. either. Any help on what I need to do or purchase would be greatly appreciated.
