Using Bluetooth and the FM transmitter to transmit phone calls over the stereo was easy and made phone calls easy to hear. The super-bright, white backlit screen would be reason enough to upgrade to the nuvi 660, especially given its newly reduced pricing. Add Bluetooth, traffic data, an MP3 player, photo viewer, travel guides, and long battery life, and you've got yourself one great GPS. At its core, navigation on the nuvi 660 is excellent. NAVTEQ mapping data and a sophisticated routing engine produced reliable and efficient routes.

The nuvi could be built a little more solidly, but there's really very little to complain about - this is an excellent GPS. With its recently reduced price, the Garmin nuvi 660 has raised the bar on in-car navigation and is clearly the GPS to beat. I can, without reservation, enthusiastically recommend the nuvi 660 for anyone looking for a full featured GPS with a big screen and lots of features, all in an easy-to-use package.
