2003 chevy monte carlo. I replaced the radio with a factory unit but it does not turn on. I need the unlock code, thanks.
JK: Unlike older vehicles that you can enter in a radio unlock code, todays vehicles do not function that way. After a radio replacement, the radio must be 'set up' using a dealer scanner. The procedure sets up country of origin, speaker options, chime level, and learns the cars VIN#. The only way to do this is with a dealer scanner. Be prepared to pay approx. 1 hr. labor.
