54 Audio
CD audio/DVD audio and MP3
i Discs with copy protection do not comply
with the CD audio standard and in some cases
cannot be played by COMAND.
When playing copied discs, problems may occur
with the playback.
A wide variety of discs, disc writing software and
writers are available. Due to this variety we can-
not guarantee that the system will be able to play
discs that you have written/copied yourself.
There may be playback problems with user-
burned CDs with a storage capacity of more than
700 MB. These CDs do not meet current valid
standards.
i When playing a DVD audio, it may be the
case with numerous albums that the last track
does not contain any music and COMAND
switches to the next track. This is due to the pro-
duction method and does not imply a fault with
the unit.
! Do not attach stickers or labels of any kind
to discs. They may come loose and damage
COMAND.
COMAND has been designed for discs meeting
the requirements of standard EN 60908. There-
fore, only discs with a maximum thickness of
1.3 mm can be used.
If a thicker disc is inserted, e.g. one which stores data on both sides, (DVD on one side, audio data
on the other side), this cannot be ejected and
COMAND will be damaged.
Do not use 8 cm diameter discs, not even with an
adapter. Only use round, 12 cm diameter discs.
i COMAND can play audio CDs with the high-
resolution surround format.
Only touch the discs at the edges.
Handle discs with care in order to pre-
vent malfunctions during playback.
Avoid scratching, leaving fingerprints
and dust on the discs.
Clean the discs occasionally with a
commercially available cleaning cloth.
Always wipe in a straight line from the
inside outwards, never in a circular mo-
tion.
The discs must only be labelled using
pens specially designed for this pur-
pose.
After use, put the discs back into the
box.
Protect the discs from heat and direct
sunlight.
i If the CD/DVD is printed on one side, this
side must face upwards when loaded. If neither
side is printed, the side to be played must face
downwards.
The system may not be able to play copy-protect-
ed CDs/DVDs.

(appr. 50 km/h), your vehicle is covering a
distance of 44 feet (appr. 14 m) every
second.

connected to COMAND via the 1/8" jack
1 located inside the glovebox.
From another main function
Select “Audio” K “Audio” K “Aux” in
the Audio menu (

page 40).
i If Audio Aux mode was active last, you only
need to select “
Audio”.
Within the audio function
Select “Audio” K “Aux”.
The Audio Aux menu appears.
The medium in the external audio
source is heard, provided it is connect-
ed and switched to playback.

Treble and bass (
page 36)
Surround sound (
page 38)
i The volume of external audio sources is ex-
tremely variable. It is possible that a device con-
nected as an external audio source will sound
quieter or louder in the vehicle or that the usual
maximum volume cannot be achieved. On cer-
tain devices the volume can be set separately. In
this case, start at a moderate volume and in-
crease it slowly. In this way, you can determine
whether the system is capable of playback with-
out distortion, even at high volume.

112 Navigation
Introduction
The digital data for the map software will
become obsolete, just like conventional
road maps. Optimum route guidance by
the navigation system is only achieved
with up-to-date map software. Information
on new map software versions is available
from an authorized Mercedes-Benz Center.
You can have the map software updated
there by means of a DVD or perform the
update process yourself.
Notes on DVD discs

Only touch the discs at the edges.

Handle the discs with care in order to
prevent reading errors.

Avoid scratching, leaving fingerprints
and dust on the discs.

Use a commercially available cleaning
cloth to clean discs. Always wipe in a
straight line from the inside outwards,
never in a circular motion.

After use, put the discs back into the
box.

Protect the discs from heat and direct
sunlight.
Introduction
Safety instructions
G Warning
For safety reasons, only enter a destination
when the vehicle is stationary. When the ve-
hicle is in motion, a passenger should enter
the destination. Study manual and select
route before driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
COMAND calculates the route to the desti-
nation without taking account of the follow-
ing:

Traffic lights

Stop and right-of-way signs

Lane merging

Parking or stopping prohibited areas

Other road and traffic rules and regula-
tions

Narrow bridges
G Warning
COMAND may give incorrect navigation
commands if the data in the digital map
does not correspond with the actual road/
traffic situation. Digital maps do not cover
all areas nor all routes within an area. For ex-
ample, if the traffic routing has been
changed or the direction of a one-way road
has been reversed.
For this reason, you must always observe
applicable road and traffic rules and regula-
tions during your journey. Road and traffic
rules and regulations always have priority
over the navigation commands generated by
the system.
G Warning
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.
