if you go the route that jmbear328 has gone with the HD zumo 665 and NIM module then yes everything will work with the NIM through your system

If you have a headset or radio that has Bluetooth and supports A2DP Bluetooth protocol then yes you can stream XM, SD Card, and GPS turn by turn directions through that device. The trick is getting it connected to do so but once connected it's great.

 

Ok....I was on the fence as to which GPS unit to go with. If the XM was going to be a pain I was going to go with the 660 instead of the 665.

 

Having XM would be great if not for the problems with the volume.
