XM radio installed.
Thanks to all of your help and research. I received a replacement Soundgate PIOGM1V2 module and everything works fine. Guess I got a bad one the first time out.
I also ordered the RCA pass through cable so I can listen to another source. Im thinking a DVD/TV tuner that I can mount next to the XM receiver under the seat.
I'll save that project for another day.
Special thanks to Aces Full, Patriot, and Klaus. Oh ya and to soundgate for rushing out the replacement part with no hassle.
