Anti-theft Feature

WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

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

Disconnecting the battery.
Disconnecting the audio-navigation unit connector A (24P).
Remove the No 15 (10 A) fuse from the under-hood fuse/relay box.

After service, reconnect power to the audio-navigation unit, and turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode Enter the 5-digit anti-theft security code, then select Done

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 navigation unit. To get the serial number and the code, do this:

Press and hold the MENU, MAP/GUIDE, and CANCEL buttons at the same time.
At the select diagnosis items screen, select Detail Information & Settings, select Unit Check, then Navi ECU (see Start-Up Procedure And Diagnostic Menu ). 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 5-digit audio-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 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 underside label which is located on the audio-navigation unit in the cargo area.

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