INFORMATION
The USB Audio Interface is only available as a factory-installed option and cannot be retrofitted.

The USB audio interface allows the connection of compatible MP3 players, such as an Apple iPod Generation4 or higher, to the vehicle and operates it through the vehicle's audio controls.

In addition to MP3 players, audio files on USB sticks can also be played through the USB audio interface.

Only audio files can be played. Accessing other files such as videos is not possible.

The USB audio interface currently supports the following compressed formats:

MP3 (mp3)

AAC (aac, m4a, m4b)

WAV/PCM (wav)

WMA (wma, asf)

Playlists in M3U format

NOTE: WAV files are not supported in playlists.

It is possible to access all stored audio data directly through a playlist, as well as searching for genre, artist, album or title. However, the sorting and displaying of audio files in the vehicle can only be carried out correctly, if all the data stored on the MP3 player (e.g. ID3 tags) contain Roman characters exclusively. Playlists need to contain absolute path indications if the audio file is not located in the same directory as the playlist itself.

Storage of the device and first installation

Observe all operating and storage instructions for the device if the iPod, MP3 player or USB stick is stored in the vehicle. It is recommended to not store iPods, MP3 players or USB sticks in the vehicle for any length of time, since extreme environmental conditions (temperature, humidity) may cause damage to the device.

Upon initial connection of an iPod, MP3 player or USB stick containing large amounts of data, audio files can be only accessed through the directory structure of the device. The search by genre, artist, album or title only becomes available after the corresponding file information has been transferred to the vehicle. The performance of an iPod, MP3 player or USB stick in the vehicle such as duration of synchronization or operation speed depends on the storage capacity and technology of the device as well as the number and the format of stored audio files (e.g. the synchronization of a USB stick with 8 GB of flash storage can take up to 10 minutes; longer synchronization times could be due to device specific characteristics. During this period of time music titles can be selected through indexes and file names).

Should the interaction of an iPod, MP3 player or USB stick with the USB audio interface not function correctly, it may also be due to defective or unsupported encoding of audio files (e.g. bit rates bigger than 256kbit/s).
