Pros: It works.
Cons: Couldn't listen to commands through my car FM radio.

It would be difficult for me to rave enough about the Garmin 660, which I selected because it was GPS Magazine's GPS of the year. Simply put: it works. That's saying a lot for an electronic device, inasmuch as almost all that I buy come replete with difficulties, complications, and defects of varying degrees. The Garmin 660 does exactly what it says it will do, faultlessly and easily.

I was prepared to struggle through the owner's manual because I have never used (or for that matter, seen) a GPS before. But, I started to fool around with the GPS and after a few moments of self-exploration, I was in my car with the Garmin and I was operating it well. I do plan to read the manual to see if there are some features I'm unaware of, but, frankly it's not necessary. I couldn't imagine traveling to any unknown place or address without having the Garmin with me. It's as important to me now as my cell phone.
