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 low-
er right of some audio displays.
Gracenote Media Database

65 Audio
CD audio/DVD audio and MP3
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 recognise 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 art-
ist, 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
Switching to CD audio mode
(

page 60).
Select “CD” K “Read CD Database”.
Depending on the previous status, the
function will be switched off C or on D.Updating the Gracenote
® Media
Database
As new music CD releases occur it is nec-
cessary to update the Gracenote Media
Database. Optimum Gracenote
®
music recognition function is only
achieved when the most up-to-date data-
base is available in your vehicle.
You can have the music recognition soft-
ware 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
(

page 113).

DVD video
If the vehicle is travelling faster than ap-
proximately 3 MPH, the picture will switch
off automatically in DVD video mode.
The following message will then appear in
the display: “In order not to distract you
from the traffic situation, the picture is fad-
ed out while the vehicle is in motion.”.
As soon as the speed falls below approxi-
mately 3 MPH, the picture switches back
on again.
i When playing copied discs, problems may
occur with the playback.
A wide variety of disc-writing software and writ-
ers are available. Due to this variety we cannot
guarantee that the system will be able to play
discs that you have written/copied yourself
! Do not attach stickers or labels of any kind
to discs. They may come loose and damage
COMAND. Labels may also cause the disc to
bend, which may result in reading errors and
problems with disc recognition.
! COMAND has been designed for discs meet-
ing 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, 12 cm diameter discs.

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.
