1. Turn the ignition switch ON (II).
2. With the audio unit turned off, push and hold the "SEEK SKIP " (A) and "CH DISC" (B) buttons. While holding the buttons, push the "VOL push PWR" knob (C) to ON.
3. The sub-display will show a U and a 4 digit number (A) (example U1234). These are the first four digits of the serial number. The display then changes to a L and a 4 digit number (B) (example U5678). These are the last 4 digits of the serial number.
4. Use all 8 numbers as the serial number when using the Interactive Network (IN) system to retrieve the 5 digit anti-theft code.
