Serial Number Display Mode

To obtain the audio unit serial number on a vehicle, do the following:

NOTE: This procedure can only be performed when the battery power is disconnected from the audio and the audio unit displays "CODE."

Turn the ignition switch to the ACC (II) or ON (II) postion.
With the audio unit turned off, push and hold the "1" and "DISC 6" buttons. While holding the buttons, push the VOL push PWR knob to ON.
The display will show an 8 digit serial number.
Use all 8 numbers as the serial number when using the iN (Interactive Network) to retrieve the 5 digit anti-theft code.
The serial number display mode ends when you turn the audio unit off, or turn the ignition switch off.
