2010 MERCEDES-BENZ E-Class SEDAN use

There may be playback problems with
userburned 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 production 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. Therefore, 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 discs with
a diameter of 12 cm.
i COMAND can play CD Audio with the high
resolution surround format.
Notes on the Care of CD/DVD Discs
R Only touch the discs at the edges.
R Handle discs with care in order to prevent
malfunctions during playback.
R Avoid scratching, leaving fingerprints and
dust on the discs.
R Clean the discs occasionally with a
commercially available cleaning cloth.
Always wipe in a straight line from the
inside outwards, never in a circular motion.
R The discs must only be labelled using pens
specially designed for this purpose.
R After use, put the discs back into the box.
R Protect the discs from heat and direct
sunlight.

Gracenote®
Media Database
i This function is only available in CD Audio
mode.
CD information including album title, artist
name and track name is obtained from the
Gracenote ®
Media Database. A version of the
Gracenote ®
Media Database is stored on the
COMAND’s hard drive. Access to this
database is indicated by the Gracenote logo
being displayed in the lower right of some
audio displays.
Many audio CDs contain CD text. COMAND
uses the information contained in this text for
displaying the name of the artist, album and
track.
If the audio CD does not contain any CD text,
COMAND can recognize unknown audio
tracks in CD Audio mode with the aid of the
Gracenote Media Database. For this to
happen, the corresponding information must
be stored in the Gracenote Media Database
and the “Read CD Database” function must
be switched on.
If this is the case, COMAND provides the
corresponding data, such as name of artist,
album and track, in the corresponding
displays and lists.
If COMAND accesses the Gracenote Media
Database while reading an audio CD, the
following information is displayed:
Switching "Read CD Database"
Function On and Off
XSwitch to CD Audio mode ( Y page 139).XSelect CD£ Read CD Database .
A list opens from which you can select the
desired data. Select None if you do not want
to display any of the data.
Updating the Gracenote ®
Media
Database
As new music CD releases occur it is
necessary to update the Gracenote Media
Database. Optimum Gracenote ®
music
recognition function is only achieved when
the most up-to-date database is available in
your vehicle.
You can have the music recognition software
updated at an Authorized Mercedes-Benz
center by means of a DVD or perform the
update process yourself.
i The Gracenote ®
Media Database is
updated at the same time as the map
software ( Y page 48).
Setting Audio Format
It is only possible to set the audio format in
DVD Audio mode. The number of available
audio formats depends on the DVD. The
content of a DVD Audio is called the “album”,
which can be divided into a maximum of nine
groups. A group may contain, for example,
music of different sound qualities (stereo and
CD Audio/DVD Audio/MP3143AudioZ

multi-channel formats) or bonus tracks. Each
group can include up to 99 tracks. If a DVD
Audio only comprises one audio format, the
“Group” menu item(s) cannot be selected.XSwitch to DVD Audio mode ( Y page 139).XSelect DVD-A£Group .
