1. that is correct the radio needs to see the vin number of the vehicle all 2002 to 2007 gm radios have that problem there is not a code to input on the radio
    the only way to make them work is if you find a mechanic with a scann tool for gm vehicles he needs to erase the vin number and the radio will turn on look i did that for a display http://www.partydown.com/pics/pievegas.j…
