I hope these pics attach properly. They're kind of crummy but I did the best I could (Sad, but true). The module is located behind the rear seat on the passenger side. It is accessed through the trunk. The good news is that there are only two "friction" fasteners holding the entire rear panel in place. They are connected to either side of the plastic, rear seat "pass-thru" box. Remove these, fold the back panel upwards and the Onstar module is immediately visible and accessible to the right side, behind the passenger seat. Installation was a snap and the thing works. I'm thrilled!! (Well, the pics are in reverse order but I'm sure you could figure that out. Good luck!)

Thanks for the tips!

Thanks, I found it and plugged the bluetooth box into it and everything works but I have a little red light that flashes on and off. How can
I correct this problem? My instructions said to just plug in the two larger wires and says nothing about the red light blinking. It is one of
the small green lights on the far right side of the mirror. bmorgan
