I know the zumo 665 had some problems early. Does anyone know if firmware updates have fixed those problems? I like the hard buttons on the 550 and it seems like the only significant improvement of the 665 over the 550 is stereo Bluetooth.
I am looking at these two units because I have been an avid XM listener for about six years and would like to add that capability to my NT.
