Well, I was able to get a Sirius receiver from eBay (P/N 140) and I hooked it all up but I don't get the SIRIUS selection on my radio. I have an 01 but I have the Business CD and the version is SW 46-00-50, so it should be fine according to all the docs. I thought I had the right tuner version since it already scrolls the display when I am on FM stations that broadcast channel/song info but maybe I am wrong with that thinking.
Can anyone assist me with troubleshooting? I have the CD Changer and that powers up without an issue and I get power at the connectors at the back of the unit.
Can the guys at Circle BMW help me with getting an upgrade to my tuner if necessary?
