I just purchased a Kenwood KDC-BT755HD for my 2006 mustang gt. I have the shaker 1000 system in it already but I cant use my phone to listen to music so I went this route. I bought the harness I needed to use for the shaker system and all that good stuff. I unplugged the factory 6 disc and removed it. The problem I am having is the (red) wire on the harness that is for the power switch is getting no voltage from the harness. I checked EVERY single fuse in both panels. Is there any place I can tap in from or does anyone know a solution. I ran the red wire to the yellow wire to power up the DU to see if I had all the speakers working. The only problem is that when the DU is in HD Radio mode all my subs work perfectly fine and dandy, but when I switch to Bluetooth they don't work. They only work with the HD Radio source. Why is that? Is there a fix? Ive spent all day on google and cant find anything. Someone please help im going crazy with no music.

 

If there is no blown fuse, uou could tap an ign fuse in the panel. As far as the sub issue, mostrradio's with bt have a setting where it only works on front speakers. You will need to set it to all speakers. Then everything should work.
