Anti-Theft Feature

The navigation system has an auto anti-theft protection circuit. When any of these actions occur, the unit enters its anti-theft mode:

• Disconnecting the battery.
• Disconnecting the navigation unit connector A (8P).
• Removing the No. A2-4 (+B Fl MAIN) (30 A) fuse from the main under-hood fuse/relay box or No. B15 (20 A) fuse from the under-hood fuse/relay box.

After service, reconnect power to the navigation unit, and turn the ignition switch to ON (II). There are two ways to exit the anti-theft mode:

• Press and hold the VOLUME/POWER knob for at least 2 seconds. The audio-navigation unit automatically checks the VIN in its memory and compares it to the VIN sent from the PCM. If they match, the audio-navigation unit exits the anti-theft mode. If they do not match, like you substituted a known-good audio-navigation unit (including the HDD), you need to enter the anti-theft code.
• Enter the 5-digit anti-theft code.

If the code card is lost or unavailable, you can get the code from the 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 DEST/ROUTE, MAP/GUIDE, and CANCEL buttons at the same time.
• At the select diagnosis items screen, select Detail Information & Settings, select Unit Check, then 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 Anti-theft code inquiry option on the iN to look up the 5-digit 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 5-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 upper label which is located on the audio-navigation unit in the dash.

The HDD and audio-navigation unit are mated to each other and can only be mated to a new unit. If someone tried to put a stolen HDD in another audio-navigation unit, or insert their HDD in a stolen audio-navigation unit, the two Components cannot mate and a HDD read error appears on the display.

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