I bought this one by accident and I needed a different one for the trailblazer with the bose system. This one is for a GM with out the bose system and to retain onstar.
Its new but the only issue (my dumbass) while finding out I had the wrong part I snipped the wrong wires off. The 14 pin harness for the device is still good as I taped the connections back up on the harness and it works.
Since I snipped the wires I cant return to crutchfield.
Asking $50 shipped to US only paypal will do.
