Hello all, I just bought a Nuvi 40 and I'm a bit new to the whole GPS arena. When I plug the Nuvi into the computer, I'm able to view the maps that came on the unit in Basecamp. When I unplug the unit, I'm no longer able to view the maps in Basecamp. Is there a way to view those maps without the unit plugged into the computer? (Interestingly enough, with a little searching, I've found the maps in a subfolder of Garmin Express saved on my computer taking up a whole 1.4 GB of space! I tried to install them using Garmin MapInstall but they still do not show up in Basecamp without the unit installed. Really aggravating if they're on my computer taking up that much space and I can't use them!) Thanks in advance! P.S. I'm using a Mac by the way.
