I saw one a friend has at work and it was clear enough for me plus you can zoom in on the area you want to see.. I am not exactly sure on what you want but it is top of the line in GPS sytems right now with an option to down load a satilite pic as well. Can also show you an airiel image as if you was in an airplane.. For me it has alot of great features that nothing else can compare to..Good Luck on what you decide.
