The best in GPS

The Garmin Nüvi 660 ($964.27) boasts a bright 4.3-inch screen and clear maps. Snazzy extras include an MP3/audiobook player; hands-free phone use; the ability to route audio through car speakers; an antitheft pass code; and optional upgrades, such as travel guides and traffic information. The Nüvi's voice directions are easy to follow, and routes recalibrate quickly. The touchscreen menu system is straightforward. The Nüvi acquired satellites rapidly, but entering destination data takes too many steps, and Garmin's maps lack fine detail. Plus, the Nüvi occasionally insisted on a clearly inferior route.
