Locked Radio

Ok this is what is happening, each radio has a serial number that is also programed in the bcm. When you turn your key on it checks the radio through a data wire and then turns on the radio, since you got a radio out of another vehicle, your car will not recognise the serial number of the new radio, to fix the problem take it to the dealer they will reset your bcm to the new radio serial number.
