Magellan's new top-of-the line GPS device would surely meet the needs of even the most demanding users. The thin Maestro 4250 comes with a 4.3-inch widescreen display, a built-in traffic receiver for live updates, and a robust six-million points of interest (POI) database. In addition, it integrates with the AAA TourBook to display listings of restaurants and accommodations, local attractions, approved auto repair shops, AAA office locations, and more. This high-end model also offers text-to-speech functionality and a Bluetooth phone interface. Perhaps the most notable feature is voice command, which you can use to control many of its functions hands-free.
