Garmin nuvi 680 Car GPS Receiver

I've researched these units for weeks, bluetooth or not, FM transmitter or not, etc. etc. for the cost difference between all the nuvi models this is by far the best deal! I was torn between the 680(purchased), the 660, and the 750-780. Ebay wise the 680 when it includes the MSN transmitter is a steal, MSN alone is 90-120$, the 660 sells for around the same price as 680's but has a standard car plug, no MSN transmitter(its in the plug!!!) For me, the tricks with the FM transmitter, the bluetooth connections to your phone and the mp3 broadcast to FM all working seamlessly and are worth 3 times the sale price of any of the 680's available. You are getting a truely hands free bluetooth car kit, and a high quality mp3 player with an FM broadcast option that work in tandem with the navigation system. Listening to music, it pauses, gives you the next direction, then resumes the audio play, or if the phone rings, theres no messing with the radio or worrying about who's calling, it displays caller id on the GPS! ONE DEVICE-----REPLACES 3 loose items in the car.
The reason I chose 680 ofer the 750-780 models was price. For the number of times you would actually program a ROUTE or download a pay for service route from Garmin it's not worth the extra $100 average price difference.
I've loved Garmin for years but have been dissapointed in their product advances in recient years until now. GO GARMIN...BUY A NUVI. You won't be dissapointed.
