It is no wonder that Garmin nüvi 660 4.3-Inch Widescreen Bluetooth Portable GPS Navigator is the best seller electronics item in Amazon website. The NUVI 660 has it all! The price that Amazon offers is incredible for such a full featured GPS unit. Turn by Turn, says street names to make navigating easier, different voices and customizable vehicle icons make it fun too. I love the MP3 player and the ability to play it on my radio system. I use the bluetooth phone everyday, works great. The only issue I can find is the mounting kit is only OK. We can't mount it on windows in CA and the adhesive wasn't strong enough to hold it. Other than that, great system, well worth the extra money for the MP3 and Bluetooth if you are wondering. .. You simply can't go wrong with this product. Outstanding system at excellent price in Amazon.
