I know my deck has a Aux-In per the book. Now I am not sure HOW I can do this so it works well.

My deck is a Pioneer deh-p3300. I also have the XM going into it by the IP-BUS which per the book says that is used as the aux-in? Now if that was used as the Aux-In how can I have both my XM and empeg work? It says I can get a adapter to adapt a RCA input to the IP-BUS, but my XM again is going through that channel. Anyone else here have a Pioneer deck with the same situtation?

I think I can get it to work by using the output RCA the deck has to the AUX in of the MP3 to get my radio stuff and XM but that seems a bit more of a pain to do when I want to use the XM or radio. Let me know guys!
