Hey Brian, thanks for the reply. The pin out you posted is for factory nav but I don't have that, is the wiring the same at the back of the CD player? Your saying that there are pins on the radio but no wires in the harness that go back to the dsp amp for the rear channels? The part number for the pigtails are those for the round connectors as you shown in your alt wine fix post? Do you know what the part numbers are for me to "prep" the system for adding the factory Sirius tuner?

Thanks
Dave.
