Anti-Theft Feature

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

• Disconnecting the 12 volt battery.
• Disconnecting the audio-navigation unit connector A (24P) and C (8P).
• Removing the No. B1 (15 A) fuse from the under-dash fuse/relay box.

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

If the code card is lost or unavailable, you can get the code form the interactive Network (iN) using the navigation system serial number. The system serial number can easily be obtained without removing the audio-navigation unit. To get the serial number and the code, do this:

• Press and hold the MENU, MAP/GUIDE, and CANCEL buttons for 3 seconds.
• At the select diagnosis items screen, select Detail Information & Settings, select Unit Check, then ECU Info (see ECU INFO.  ). The system runs a brief diagnosis, then the audio-navigation unit serial number is displayed at the bottom of the screen.
• Use the navigation anti-theft code inquiry option on the iN to look up the 4-digit navigation anti-theft code.

The iN may display more than one code for a given serial number. This is because serial numbers are not unique. You may have to try more than one 4-digit code. If no code is shown, or if the code(s) given do not work in the audio-navigation unit, contact the Automobile Warranty department.

Alternatively, you can find the serial number on the underside label which is located on the audio-navigation unit in the dash. When replacing the audio-navigation unit, be sure to give the customer the new anti-theft security code.
