The Nuvi 660 is quite similar to the Nuvi 680. The differences are fairly minimal as both feature Bluetooth connectivity, the entertainment package along with other travel tools. The Nuvi 680 still features the exclusive MSN Direct service which is an incredible dynamic information service allowing you to check gas prices, movie times, traffic, and many other things. The Garmin Nuvi 660 does have it’s own trick up its sleeve with integrated FM traffic receiver to receive traffic conditions quite well. Both are excellent models that feature the notable widescreen display as well as many similar features that make both units quite comparable.
