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 audio-navigation unit connector A (24P).
- Removing the No. 1 (100 A) fuse from the battery terminal fuse box or the No. 1 (10 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). 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 exits the anti-theft mode. If the audio-navigation unit does not exit anti-theft mode, like in cases where a known-good unit (including the SD module) was substituted for testing, enter the anti-theft code.
- Enter the 5-digit anti-theft code.
If the code is lost or 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 MAP/GUIDE, the DEST, and the CANCEL buttons at the same time.
- At the select diagnosis items screen, select Detail Information & Setting, select Unit Check, then Navi ECU. 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(s) given do not work in the audio-navigation unit, contact the Automobile Warranty department.
The SD module 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 SD module in another audio-navigation unit, or insert their SD module in a stolen audio-navigation unit, the two components cannot mate and a SD module read error appears on the display.
When replacing the audio-navigation unit, be sure to give the customer the new anti-theft security code.
