I have a question for those with the Zumo, or any Garmin GPS with preloaded maps. What do you do when they come out with the next version of City Navigator? Is there a way to update the built-in maps?
For context, I currently own a Streetpilot III, which only stores base maps. All detailed maps are stored on a Garmin memory module. I have to load the detailed maps for the area I'm traveling onto the memory stick for them to be available to the GPS unit. It seems that with the new units, you don't have to load maps into the GPS, only routes and waypoints.
