On my navigation screen the background colors seem to be green and gray, but I don't know the significance of the two colors. Can anyone offer a key to these colors?
At first I also thought the green might be parks (since that's the way paper maps seem to work) but it's definitely not. I realized that yesterday when sitting in the Sam's Club parking lot. I noticed everything around me was green on the screen, including Sams's, Walmart, the entire shopping center, and the commercial district around it. Some residential areas are green, some gray. The same is true of commercial areas -- some gray, some green. So far I can see no pattern.
