Anti-Theft Feature

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

The navigation system and audio system have a coded theft protection circuit. Make sure you have the anti-theft code before:

Disconnecting the battery.
Disconnecting the audio-navigation unit connector A (24P).
Removing the No. 5 (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). Turn the audio power on, enter the 5-digit anti-theft code using the audio preset buttons.

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 MENU, 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 (see UNIT CHECK (QUICK CHECK) ). 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 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 dash.

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