The receiver is the SCC1 and the interface to the HU is CD-SB10 Are those the correct part numbers?

I have a Z110BT that has been flashed to a Z120BT. I recently purchased the Sirius modules for it (Sirius to Pioneer interface and the Sirius receiver). I hooked up everything up and can see the channel I am on as well as what song is playing, but there is no audio. I thought it may have been the Sirius equipments, so I replaced both of them but same problem. This leads me to believe that it's the Headunit. Any ideas?
