Thanks (longrides), I've got my local HD getting two different mounts in now. I'm at work now and won't be home until the 9/8/11. Both (car and truck) already has a built in XM, but thanks anyway. Thanks for the reply

 

Hell All, I have the Zumo 660 HD GPS/MP3 Player. It is professionaly installed at HD with the expensive wiring harnesses and other items. When I play the music through the GPS (no navigation routes are in use) the vlume on the radio fluctuates and when I use the volume button on the handlebar, the Nav/Phone is displayed on the HD radio? Thanks for any help or guidance...

Also, to answer some of the other Qs in this string, when the GPS is working properly with the HD install kit, I here the msic and GPS directions voice through the radio. When a turn is coming up, the music volume is reduced and the ladies voice tells me when to turn.
