I've seen the SIR-PNR1 and 2, the CDSB10 and the SCC1.

Which one do I need? I dont want to hook up another radio, I just use the AVIC as the tuner.... I've read that the SIR-PNRx's are garbage (hence the discontinued) so would I just need the CDSB10? Does the SCC1 just allow for an additonal radio along with the AVIC? If so I dont need the extra cost....

Anyone? Bueller? Anyone?

You need both the SC-C1 and the CD-SB10. The SC-C1 is a universal tuner that takes the signal from the Sirius antenna and outputs it to the CD-SB10. The CD-SB10 is a Pioneer specific part that interfaces to the X910BT and allows the 910/710/etc to play the Sirius stations.

Looks like you dont need the SC-C1.....
