Daewoo — Frequently Asked Questions

    Enter the 8-digit serial number stamped on the metal body of the radio.

  • What happens if the code is entered incorrectly?

    Most radios enforce a 15–30 minute wait period (Wait / Safe / Error) after incorrect attempts. Leave the radio switched on with the ignition on until the code entry screen reappears.
