Magellan Maestro 4000

Pros: Acurate, night mode automatically, recalculates automatically

Cons: The detour feature not the best and many points of interest are not programed.

Summary: I work for a fire department and we have a propriatory GPS guidence in our dispatch computers that calculate best route to the call. The Magellane is MUCH better. I whish our dispatch computers had magellan maps and programed to recalculate if you get off the route, go to night mode and chose the best route to the call as the Magellan does. The only weak points that I have found are that the detour function often takes you WAY out of our way and trying to find many restaurants that I know are in the area the Magellan 4000 doesn't list. Otherwise this is a great product and I use it all the time, sometimes to map my route but mostly just for fun.
