PROS The StreetPilot will please both Luddites and tech geeks. The windshield mount is straightforward and strong; a simple main menu asks you basic questions "Where to?" -- and guides you with spoken directions that include street names. Delve into the c580's advanced capabilities and there's even more to like: You can link a Bluetooth phone for hands-free calls or see gas prices two exits down the freeway courtesy of MSN Direct (free for 12 months, $50 per year thereafter).

CONS The StreetPilot is relatively bulky and heavy, and considering the price, its screen is too small at 3.5 inches.

BUY THIS ONE IF ... You're willing to pay top dollar for best-in-class functionality and an idiotproof interface.
