Rating: - Very good navigator
Very easy to use. Very helpful on road.
The car charger is not good though. The one came with the navigator was broken. The provider sent us the second one. It was broken too! I called Garmin and was told the car charger for nuvi 660 was out of stock. Because I was in hurry for a trip so they sent me a car charger for nuvi 650 that works for 660 but with no traffic senser. If I want 660 charger later I have to call and do exchange with Garmin...lots of work to do to fully enjoy it...
Rating: - Mediocre directions and poor interface
About 1/4 of the time, it gives you some ridiculous route that is not the shortest or the fastest. It's not as good as Google maps by a long shot. The interface is lame - it's easy to use but it's missing many features. For example, you can't easily change the route the GPS has selected for you by dragging the route lines like you can in Google maps. I wouldn't recommend this device.

I love this thing! It makes it so easy to travel alone now since my son has gone away to school and he was always my navigator on trips. Like the cell phone...how did we ever live without them?
Rating: - Garmin nuvi 660
I am very pleased with the nuvi 660. It has met most of my expectation. My only complaint is some times its routing in cities is not always the most logical.
I find the Garmin nuvi very easy to use. Such a pleasure to be able to drive and not worry about getting lost. Being a bad map reader this GPS navigator has been a blessing. Could not be happier.
