Anti-theft Feature

WARNING: This page is about a different car, the 2008 Acura TSX, 2007 Acura TSX, and 2006 Acura TSX. However, it is still accessible from the selected car via links, so may be relevant.

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

After service, reconnect power to the navigation unit, and turn the ignition switch ON (II). Enter the 4-digit anti-theft security code, then select "Done".

If the code cannot be found, use the interactive Network (;'N) to look it up. You can view the serial number in one of the Navi ECU diagnostic screen (see UNIT CHECK  ). Alternatively, you can get the serial number from the navigation unit in the trunk.

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