Part Two
Audio System Description
USB Adapter ('11 model)
The premium audio system can play digital music from portable audio players, a USB drive, 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 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 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
- 2.0 Full speed USB capable (maximum speed is 12 Mbps)
- At least 256 MB storage capacity
- USB formatted to be compatible with Windows-based operating systems
- 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 unit software is constantly updated.
The audio unit displays the folder differently than what you may see on your PC because the audio unit only recognizes two folder levels. The audio unit overwrites the data for the track order when you connect the USB device. The audio 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 unit's memory so when you reconnect the same USB device, the audio 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 Function List
USB Music Search
When you plug in a USB device, the audio 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.
USB with Audio Units
When you plug in a USB device, the audio 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 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 unit automatically creates a folder titled ROOT, and lists all these playable music files in it. If your customer complains that they cannot 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 unit automatically creates a folder named ROOT (A).
