Anti-theft Feature

The navigation system and audio unit have a coded theft protection circuit. Make sure you have the anti-theft security code before:

After service, reconnect power to the navigation unit, and turn the ignition switch to ON (II). Enter the 4-digit anti-theft security code, then select Done.

If the code cannot be found, use the interactive Network (iN) to look it up. You can view the serial number in one of the ECU Info diagnostic screens (see UNIT CHECK (QUICK CHECK)  ). Alternatively, you can find the serial number on the underside label which is located on the navigation unit in the trunk.

When replacing the navigation unit, be sure to give the customer the new anti-theft security code.
