I have a 1997 Chevy Blazer with a factory radio (model 16211095) installed. Looks like this http://www.radiosandmore.com/Large_i...g/16211095.JPG It has an AUX button on the front and I'm sure there is a port on the back. Anyone know how to make use of the port, I'd like to hook up my XM radio to it? I have looked at a couple of products, but no one lists compatibility with the 97 Blazer. I started to take it out to look at the back, but it was too much work just to see the back of the thing
I searched the part number and didn't come up with anything useful, I could really use a picture of the back or a wiring schematic for it.
