Summary: Love the GPS and the endless cool features it has(Have the nuvi 660 w/2009 map) Pros: The external antenna keeps reception indoors or outdoors, easy to use as with most Garmin GPS, The traffic function if set up is awesome (saved me from a couple jams), Bluetooth is fun (reads text messages to you) and so is audible book (reads books to you ex: bible, etc; free trials are givin but you pay afterwards). The sound on MP3 is good and fm transmitter is nice feature too.
Summary: I got my Nuvi 660 about a week ago and have been playing with it for the last few days. The unit is really easy to use with a big clear display that you can see well even in full sunlight. I will only highlight some of my observations/frustrations. Since I am in the Gatineau, Quebec area the 660 is really comical in the speech of French names when using it in English. Also, street names are preceded by rue(street), chemin(road), etc.
