I am considering adding a GPS to my '12 RT-S and wonder if anyone can explain why the Garmin 660 is so expensive. There seem to be many units of different brands designed for cars that offer the same features that cost hundreds of $ less than the Garmin. I looked up the 660LM on the Garmin sight and it is $650!! Is there something special about this unit that makes the price that high?
