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 or the DC-DC converter.
• Disconnecting audio-navigation unit connector F (18P).
• Removing the No. GF (20 A) fuse from the under-dash sub fuse/relay box B.

After 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 Enter PIN Code 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 the anti-theft mode, 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 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 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 the System Diagnostic Mode - Refer to: Navigation System Diagnostic Mode (2015-17),  or Navigation System Diagnostic Mode (2018-19) , and select Detail Information & Setting, then select ECU Info in Unit Check menu. 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 (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 the 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 client the new anti-theft security code.
