I have finally found all the files for 3.0, and downloaded them, and isntalled it. Went very easily...

 

I am only having one issue that I can't find a answer for... When you are on the XM, and only XM, when you turn the volume up, the channels change on the XM well, and it keeps doing it...

 

Anyone have any thoughts on how to fix this little problem?

 

So far, I am really pleased with the way it works in the old 95 Tahoe...

 

 

Well, I did find the solution to the issue. (it also effected the radio on AM/FM as well)  Turns out the PAC unit for the steering wheel controls was the culprit. Unplugged it from the back of the radio, and all is well.
