How to Troubleshoot the Audio System

Anti-Theft Feature

The audio-navigation unit or the audio unit (with multi-information display) has an anti-theft protection circuit. When one of the following occurs, the unit enters the anti-theft mode.
* Disconnecting the battery.
* Disconnecting the audio-navigation unit connector A (24P) or the audio unit connector A (24P).
* Removing the No. A1-6 (100 A) fuse or the No. A29 (10 A) fuse from the under-hood fuse/relay box.

After service, reconnect power to the audio-navigation unit or the audio 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 (Power) knob or the POWER (Power) button for at least 2 seconds. The audio-navigation unit or the audio unit automatically exits the anti-theft mode. If the audio-navigation unit or the audio unit does not exit anti-theft mode, like in cases where a known-good unit 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 or the audio unit serial number. The unit serial number can easily be obtained without removing the audio-navigation unit or the audio unit, do the following:
* With navigation: Go to Anti-Theft Future in How to Troubleshoot the Navigation System How To Troubleshoot The Navigation System.
* Without navigation: Go to How to Obtain the Audio Unit Serial Number in Self-Diagnostic Function Audio System Self-Diagnostic Function.

When the audio-navigation unit or the audio unit is installed in another vehicle (same Year/Model), you have to enter the 5-digit anti-theft security code. After that, you can release the anti-theft mode by pressing and holding the VOLUME/POWER knob or the POWER button.
