Note
Please read and observe the manufacturer's manual for the external audio
source.
External audio source connected to the AUX-IN multimedia
socket
Depending on the version of the vehicle, the multimedia socket AUX-IN may
be in a different location. Please refer to the vehicle Instruction Manual to
locate the position of the socket.
The AUX-IN multimedia socket can only be used with a 3.5 mm jack plug.
The external audio source connected is indicated by the AUX
function but-
ton in the Media selection menu . If the function button
AUX
is not displayed,
AUX must be activated in the
SETUP menu ⇒ page 52.
Connecting an external audio source to the AUX-IN multimedia socket
● Connect the external audio source to the AUX-IN multimedia socket.
● Lower the basic volume of the radio ⇒ page 8.
● Start playback on the external audio source.
● Open the Media selection menu and select the AUX
function button
⇒ page 24.
The output volume of a connected external audio source should be adjusted
to the volume of the other audio sources ⇒ page 53.
Vehicles with AUX-IN multimedia socket and MEDIA-IN multimedia interface
In vehicles also equipped with the MEDIA-IN multimedia interface the MEDIA-IN
function button is displayed instead of the AUX function button
⇒ page 30.
An external audio source connected to the AUX-IN multimedia socket can
only be played when no external data medium is connected to the MEDIA-IN
multimedia interface.
The audio source of the devices connected in the MEDIA-IN device (USB as
AUX-IN) takes priority over those connected in the RSE. Where both options
are available, make sure that there is nothing connected in the MEDIA-IN*
connections when you wish to listen to the audio source of the RSE
( ⇒ Booklet Rear Seat Entertainment) in the car.
Note
● When playback on the external audio source is stopped or the plug is
disconnected from the AUX-IN multimedia socket, the radio-navigation sys-
tem remains in the AUX menu.
● Interference may be heard if the external audio source is powered from
the vehicle’s 12-volt socket.

Audio mode
● When playing large capacity hard discs with several files and a complex
data structure (several folders and subfolders, non-playable files, etc.) it
may take some time to read the audio files. The reaction time may also be
influenced by the connected device.
● WMA (Windows Media Audio) audio files can only be played if they are
not protected by authors' rights with the DRM (Digital Rights Management)
system.
● Generally, files with anti-copy protection cannot be played (e.g. M4P).
● It is not possible to play files in 3GP format or “WMA lossless” files.
Check there are no MP3 files stored in the playlist. A playlist only defines a
certain order of play. If a playlist cannot be played, check that the “relative
paths” are correct, i.e. that the MP3 files on the data medium are actually
stored at the locations referenced by the playlist.
If an external data medium is divided into several partitions, only the first
partition with compatible audio files will be played.
Please refer to further limitations and notes on the requirements placed on
media sources ⇒ page 21.
WARNING
● The connected audio devices must be protected from possible me-
chanical damage and other kind of wear.
● We do not hold responsible for any possible damage on the connec-
ted devices.
● The connection of USB devices is sensitive to interference from mo-
bile telephones. Mobile telephones should not be left next to the USB
when this is connected, to prevent distortion.
● The connected audio devices must be protected from possible me-
chanical damage and other kind of wear.
● Objects which are not secured in the vehicle compartment may inter-
fere with driving and could result in serious injury.
WARNING (Continued)
● The external data device should never be left on the dash panel. A
sharp manoeuvre can throw the device towards the compartment and in-
jure the vehicle passengers.
● The external data device should never be mounted in the vicinity of
the airbag. If an airbag is activated it can project the device towards the
compartment and injure the vehicle passengers.
● The external data device must not be held in hand or on the legs
while driving. A sharp manoeuvre can throw the device towards the com-
partment and injure the vehicle passengers.
● Place the external data device cables so that they are not in the way
while driving.
CAUTION
Make sure that the adapter lead is not pinched or severely bent. This can
damage the adapter lead and cause functional faults.
Note
● Some vehicles with the MEDIA-IN multimedia interface mounted on the
centre armrest are also equipped with an additional compartment. The rub-
ber insert of this compartment can be removed in order to extract small ob-
jects which may have fallen inside.
● Do not connect an external media player to the radio-navigation system
via Bluetooth and via the MEDIA-IN multimedia interface at the same time,
as this could lead to limitations in playback.
● The use of memory card adapters or USB hubs can cause problems in
reading files.
