I apologize in advance to all you GPS geeks with advanced degrees in navigation.
I have a Zumo 450. I can type in a destination and get there. Wahoo!
I just downloaded Garmin for Mac: Roadtrip, Base Camp, MapManager, and MapInstall.
Here's the stupid question:
what the hell do I do now? Is there anybody willing to provide a paragraph or two on how all this works?
