You just need to purchase a PAC audio adapter (approx. $30-$40). It jumps an aux input via the XM system. I have it and it works great. The only down side is that you have to install a manual switch somewhere along with the cable. I put my switch in the ash tray so you don't see it unless it is open. Flip the switch while in XM 1 mode and the output is to the MP3 player.
I have my cable on the floor with enough length to sit the IPOD in the cupholder. If you want pictures, let me know and I'll send them to you direct so as not to suck up bandwidth on this site...
