Query: Garmin Nuvi 680 Personal Review

The Nuvi 680 is a great device, surprisingly useful features on the Nuvi 660 platform with the inclusion of the MSN Direct service. Garmin has incorporated these additional features in an easy to use way that does not detract from the overall aesthetics of the operating system.I have issues with the Bluetooth feature, were it doesn't always notice my cell phone. The MSN direct traffic feature is nice to have, but after the free year is not worth the cost for a membership. Additionally, the MSN function only work when the cable is plugged into the cigarette lighter, why...I have no idea.
