The car came with the OEM stock non-Bose (U66) amplifier and head unit, with digital OnStar, Verizon digital cell phone, and XM satellite radio.
I've replaced the Delphi/Siemens OEM head unit with a Blaupunkt Kingston MP47 CD/MP3/tuner, using PAC's OS2-CTS to retain the OnStar, door chimes, and accessory power features. The original XM Radio receiver is still installed, and I can route the audio signals into the AUX input of my Blaupunkt head unit. What's missing is a method to control the XM Radio receiver.
Does anyone have information or suggestions for either controlling the OEM XM Radio module or replacing it with an aftermarket XM unit? Thanks.

Dontchya just love it when someone responds to their own post? I started looking for GM J1850 VPW messages and landed over at mp3car.com where I found the following links regarding the XMD1000 XM Direct unit, and controlling it via a PC's serial port:

https://www.mp3car.com/vbulletin/hardware-development/41001-xm-carputer-guide.html
So for now, I'll look for one of these XMD1000 units and hopefully be able to work with it. :D
