I was hoping somebody might be able to help me out. I've got an 09 Silverado Extended cab. The truck did not come with the interior convenience package, so I don't have bluetooth, steering wheel audio controls, or auto climate controls. The truck did come with the Bose stereo in it. Yesterday I installed the factory navigation system. I also purchased a VSS harness which I tapped into the VSS wire successfully (I think). However, the VSS hardness was also packaged with a plug for the VCIM module. The problem is, I am completely unable to locate the VCIM in my truck. Can anybody give me some guidance as to where this might be located? I would really like to use the voice commands ability!
