USB/Audio Interface
The “USB/audio interface” supports the playback of audio files stored on mass storage
devices with USB connections such as USB sticks, MP3 players etc.
USB is a serial bus system that allows fast and simple connection of terminal devices to
computer systems.
The mass storage medium can be found under the “External devices” submenu in the
“CD/Multimedia” menu of the iDrive.
All USB mass storage devices that support the “USB Mass Storage Class” standard can
be connected. This includes mass storage media for the playback of compressed audio
files with a USB interface such as MP3 players, USB memory sticks, etc. The Apple
iPod
®
is also supported as from the 4th generation version.
Due to the large number of devices on the market, no guarantee can be given that every
available “USB Mass Storage Class” device will function through the USB interface. If a
device of a different device class is connected, the message “Incompatible device” will
appear.
When a USB mass storage device is connected, the contents of the device are read and
the folder structure is processed for display on the CID. A plausibility check is performed
as to whether the tracks can be played by the vehicle’s sound system.
Only those tracks that can be played are displayed.
While the database of the content (details of the music tracks is constructed, the music
files can only be selected by navigating through the folder structure. On completion of the
database, music tracks can also be selected by genre, artist and album.
Media Transfer Protocol (MTP) is currently not supported. MP3 players that use MTP are
therefore not supported. More information on the protocols used can be obtained from
the operating instructions of the mass storage device.
