Anti-Theft Feature

The audio-navigation unit has an anti-theft protection circuit. When one of the following occurs, the unit enters the anti-theft mode.

Disconnecting the 12 volt battery.
Disconnecting audio-navigation unit connector A (24P).
Removing the No. A1-6 (120 A) fuse, or the No. A29 (10 A) fuse from the under-hood fuse/relay box.

After the service, reconnect power to the audio-navigation unit, and turn the vehicle to the ON mode. There are two ways to exit the anti-theft mode:

While Anti-Theft System screen is displayed, press and hold the POWER button for at least 2 seconds. The audio-navigation unit automatically exits the anti-theft mode. If the audio-navigation unit does not exit anti-theft mode, like in cases where a known-good unit was substituted for testing, enter the 5-digit anti-theft code.
Enter the 5-digit anti-theft code. If the input of code fails 10 times in a row, the screen is locked for 60 minutes.

If the code is unavailable, you can get the code from the iN using the audio-navigation unit serial number. The serial number can easily be obtained without removing the audio-navigation unit. To get the serial number and the code, do the following:

Press and hold the EJECT button, the POWER button, and the HOME button until the Select Diagnosis Items menu screen is displayed.
At the select diagnosis items screen, select the Detail Information & Setting, select the Unit Check, then the DA Unit. The system runs a brief diagnosis, then the audio-navigation unit serial number is displayed.
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 given do not work in the audio-navigation unit, contact the Automobile Warranty department.

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