Garmin nuvi 660 Car GPS Receiver

I do over the road trucking and must find many new addresses. This unit is very good at what it does, but does not replace good directions and common sense, it compliments them. Nice to know left exits, and distance to location, etc. I would recommend it to anyone as a tool to be used while driving. Haven't used many of the features yet but may later. Bluetooth, audiobooks, etc. Traffic alerts in big cities are handy, but usually just let you know you're in for a bit of a wait. Not too many errors yet, but a few. These tools have their own little quirks. We sometimes disagree on routes and the little unit is very stubborn! Overall tho, I'd buy again.
