My 08 was made without XM. I have the XM module from my 07. My dealer refuses to try to install it, gave me some bull**** about how the head unit was reprogrammed in 08 to not allow XM.
The small issue, of course, is that, aside from the fact that GM would never have bothered to alter a head unit in the last year of production, my head unit isn't even an "08"--it's an unlocked unit off eBay. And it's exactly the same unit I used to listen to XM in my 07.
I was also told there was no way to get audio cables for a 14 year old car. In the same visit where they installed a brand new fog light in a 14 year old car.
Does anyone know if the cables are actually available and the tech is being an idiot, or am I going to have to go on a strange boneyard trip?
