GA-Net Bus Configuration

The GA-Net bus passes audio commands throughout the audio components. These commands include hard button signals, audio/XM selections, and XM station and music title names. Because the entire bus is "daisy chained" between components (see diagram below), 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.

Scheme 20

USB Adapter

'09-11 audio system with navigation can play digital music from portable audio players, a USB device, etc. when the device is plugged into the USB port. The audio-navigation unit uses the GA-NET to allow you to control the device from the audio-navigation unit when searching and playing the files. Not all players and player functions work with the USB adapter. Please see the Owner's Manual for more information.

USB Function

Music files can be stored on portable USB devices (flash drives and approved iPod products) and played through the audio-navigation unit by using the USB adapter. Although a customer can create many different folder levels on their USB device, the audio unit only recognizes two levels and automatically sorts the music to meet this requirement.

To play the music files, use the dial selector to find the folder where the music file is located, then select the album or music file (see the Owner's Manual for more information about selecting and playing USB files and approved iPod products).

USB Device Requirements

1. 2.0 High speed USB capable (maximum speed is 480 Mbps)
2. At least 256MB storage capacity
3. USB formatted to be compatible with Windows-based operating systems
4. If the USB has a security feature, like write protection, it must be turned off

There are many different USB drives, manufacturers, and configurations with new devices being released every day, which makes it impossible to test all USB devices with the audio system. Even if the USB device has all these requirements, it may not be compatible.

To check if a USB device is compatible with the vehicle, test the USB device in a known-good vehicle of the same model and year. If the USB device does not work on the known-good vehicle, assume that it is faulty or not compatible. A USB device may work on a later year of the same model vehicle because the audio-navigation unit software is constantly updated.

The audio-navigation unit displays the folder differently than what you may see on your PC because the audio-navigation unit only recognizes two folder levels. The audio-navigation unit overwrites the data for the track order when you connect the USB device. The audio-navigation unit does not modify the music files or the structure on the USB device.

Hard drives do not support overwriting the data for the track order, which is why they are not recommended.

Reconnecting the USB Device

When you disconnect a USB device, the data for the track order remains in the audio-navigation unit's memory so when you reconnect the same USB device, the audio-navigation unit continues playing from the location where it was disconnected. If a new USB device is connected, the data for the track order is rewritten and you need to select the album or music file.

USB DEVICE TABLE

USB Music Search

When you plug in a USB device, the audio-navigation unit automatically searches the USB device for playable music files. See the Owner's Manual for more information about navigating USB menus and selecting music.

When you plug in a USB device, the audio-navigation unit automatically searches the USB device for playable music files. See the Owner's Manual for more information about navigating USB menus, selecting music, and music file compatibility.

The audio-navigation unit organizes the playable music folders and files that appear on the USB device. If there are any music files that are not located in a folder, the audio-navigation unit automatically creates a folder titled ROOT, and lists all these playable music files in it. If your customer complains that they can not find some songs loaded on their USB device, recommend that they check the ROOT folder for the missing music files. If all the music files on the USB are in folders, the ROOT folder does not appear.

When there are music files not located in a folder, the audio-navigation unit automatically creates a folder named ROOT (A).

Scheme 21

Select the Track List button to see the ROOT folder (A) which is automatically created only when there are music files not located in folders.

Scheme 22

All the music files not located in folders are listed under the ROOT folder.

Scheme 23

Muting Logic

The navigation system allows voice control of the audio, the XM, the PC card, and the CD player. Voice control commands are communicated on the GA-Net (audio-navigation unit). When using the navigation TALK/BACK button, the audio is muted on all speakers and you get navigation sound on the front channels. When using the navigation or route guidance (RG), the front speakers give the navigation sound and the rear speakers continue to play. For more information, see the navigation section. The outline of the interruption function is shown in this table below.

Left/Right Channel ID

Do this test to confirm proper channel routing.

1. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit.
2. Play track No. 1 (left, both, right channel ID) at a normal, or slightly higher than normal, volume level.
3. The voice should be audible only from the channel or channels when indicated. If the channel ID is correct for each side, go to the phase test. If the channel ID is not correct, check for; Shorted speaker wire Faulty amplifier (with premium sound system) Faulty audio unit

Frequency Sweep

Do this test to find rattles or reverberation that may cause a perception of poor sound quality.

1. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit.
2. Play track No. 13 (sweep from 500 Hz to 35 Hz) at a normal, or slightly higher than normal, volume level.
3. Listen to each speaker for poor sound quality or reverberations caused by specific frequencies. Use the voice-over to estimate the frequency that causes the vibration. Use the audio unit's fader and balance settings to help isolate the channel with the problem. If you hear vibrations or poor sound quality, go to step 4 . If you do not hear any vibrations or poor sound quality, go to sound judging.
4. Choose the appropriate track from No. 14 to 25 (small range frequency sweep) or 26 to 53 (single frequencies) to recreate the frequency that caused the poor sound quality or vibration located in step 3 this aids in diagnosis of the problem. NOTE: When you get to the track that recreates the problem, select the repeat function on the audio unit, this will help you isolate the cause.
5. Replace or insulate the source of the vibrations or, if the speaker is the source of the poor sound quality, replace it.

Sound Judging

1. Do this test to compare overall sound quality, imaging, and dynamics between the customer's vehicle and a known-good vehicle. Only use a vehicle of the same model and trim level for this test.
2. Make sure the vehicle is using only OEM speakers.

1. In the customer's vehicle, set the bass, treble, fader, and balance settings to the customer's normal settings that were written down before beginning testing.
2. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit.
3. Play tracks No. 7 to 12 (sound quality, midland, dynamics, and imaging demonstration tracks) at a normal, or slightly higher than normal, volume level. Write down the volume setting.
4. Listen to areas of the track that stand out as being either very clear, or poorer than other areas of the track.
5. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit of a known-good vehicle.
6. Play the tracks at the same volume level and the same bass, treble, balance, and fader settings as used in step 3 in the customer's vehicle.
7. Listen to the same area of the track that stood out as being either very clear or poorer than other areas of the track.
8. Compare the customer's vehicle's sound quality results to the known-good vehicle's results. If the sound quality in the customer's vehicle is comparable to the sound quality in the known-good vehicle, then the customer's vehicle is operating as designed. If the sound quality is not comparable, check these items in order. Loose or improperly installed speakers or other hardware that may become excited by the vibrations generated by the speakers Poor power or ground to the stereo amplifier Damaged speaker(s) Faulty amplifier Faulty audio unit
