Query: Exceeds expectations

First of all, map and firmware updates ARE available via the Magellan website - other reviewers have gotten this wrong. The 3100 is ready to go right out of the box, has a sensitive receiver, and ALL of its menus and features are intuitive. The display and maps are simple, yet clear, easy to work with quickly, and purposeful. There is no mess and using the unit doesn't require much toil and handling. Reroutes are fast, and instructions and tones are kept to a peaceful minimum.One negative is that the unit comes with a car charger only, and does not charge via the USB port.
