Audio System Description

Muting Logic

The optional navigation system provides voice control for the audio, the XM, and the CD player. Voice control commands are communicated through the GA-Net (audio unit). When using the navigation TALK/BACK or route guidance (RG), the center speaker is muted and you hear the navigation instructions through the front speakers. When using the HFL/AcuraLink, the center speaker, the rear speakers, and the subwoofer are muted and the front speakers give the telephone sound. When using the HFL/AcuraLink and RG (Route Guidance) or the navigation TALK/BACK, the center speaker, the rear speakers, and the subwoofer are muted and you hear the telephone sound and navigation instructions through the front speakers. Muting commands are passed on the GA-Net bus. For more information, see the navigation section. The outline of the audio interruption function is shown in the following table.

USB Port

The audio unit can play digital music from portable audio players, USB drivers, etc. When the device is plugged into the USB port. The audio unit uses the GA-Net to allow you to control the device from the audio unit when searching and playing the files. Not all players and player functions work with the USB port. please see the owner's manual for more information.

GA-Net Bus Configuration

The GA-Net bus passes audio and navigation commands throughout the navigation and audio components. These commands include navigation touch screen and hard button signals, audio/XM selections by voice, and XM station and music title names. Because the entire bus is "daisy chained" between components (see diagram), any open or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. The addition of any audio accessory must maintain the continuity of the GA-Net bus by installing the Y cable included with the accessory kit.

Anti-Theft Feature

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

- Disconnecting the 12 volt battery.

- Disconnecting audio unit connector A (17P).

- Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box.

When the audio unit is reconnected to the power and the ignition switch is turned to ON (II), "CODE" is displayed. Then, enter the 5-digit anti-theft security code.

If you do not have the anti-theft code, see Self Diagnostic Function for information about retrieving the anti-theft code using the IN.

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