If an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit's serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code. Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio. Refer to your owner's manual for the specific procedure. Some older vehicles (model year 2003 and older) require a visit to the dealer in order to retrieve the audio unit serial number. Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.
