location

I've taken out the radio, looked under the glovebox, looked above the glovebox, and searched everywhere online. Where in the heck is the Onstar for this car, and how do I get to it? I bought one of those BlueStar units to install bluetooth, and I'm dying to use it. Thanks in advance. Rob

Ok Ive read the forum for a few days now and I still dont know is the factory installed amp in the bottom of the center console?? Ive also read something about near the break pedel... In the book it says and I quote this "step 1:locate the amp...." which was was no $^&*ing help at all!! goping...
