So the other day I got my XM Sportscaster in the mail and quickly found out that I want it hard wired to my stereo so it can be the AUX. I have searched these message boards(along with others) and it seems installing something like this is a case by case basis. I have a 2003 Avalanche with the Bose 6 disc changer. The BIG question is, in order to connect the Sportscaster directly to my radio so it will be the AUX, what do I need? I know this forum has audio geniuses on it so any info will help greatly. Thanks guys.
