Try this link, in the post above it was truncated/misinterpreted by the BBS code, but cut and paste of the complete url worked for me. The article number is CD-RB10

Description is as follows:

"Auxiliary Input Adaptors

CD-RB10
Auxiliary Input Adapter RCA for IP-Bus Headunits"

To me that's the description of a thing that plugs into the rear of your Pioneer HUs IP-bus connector and gives you RCA inputs.

I have no idea of how the Pioneer IP-bus works, so maybe this would give you RCA out from the XM module, but I doubt it.
