I recently installed a Pioneer 5900IB Head Unit in my 2002 Mustang GT, and bought the SIR-PNR2 Pioneer Compatible Sirius Tuner. I wired everything in, and
I am getting a signal, but I am only hearing static from the radio. The
src on the headunit it set to Sirius, but I can't get it to work. I did buy the SIR-PNR2 used off of ebay and it did not come with any instructions. The only wires I had were a yellow power wire and a black ground wire, and then I had the interface card. one black end for the output from the satellite tuner, one purple end for the input to the cd-player

The tuner has been activated, but I don't know what else to do. It's grounded properly and the power wire is connected properly.

Antenna is on the roof, and connected as well.

anyone have any ideas?
