Gracenote Media Database
Introduction
This function is only available in audio CD
mode.
There is a version of the music recognition
software from Gracenote ®
, Emeryville,
California, USA on the hard disk. You will
recognize this by the logo which can be seen
in the bottom right-hand corner of certain
audio displays.
Many audio CDs contain CD text. COMAND
uses the information contained therein to
display the artist, album and track name.
If the audio CD does not contain any CD text
information, COMAND can use the Gracenote
Media Database to identify unknown audio
tracks when running in audio CD mode. This
is only possible if the relevant information is
saved in the Gracenote Media Database and
if the "Gracenote Media Database" function
is activated.
If this is the case, COMAND will display the
corresponding data such as artist, album and
track name in the relevant displays and lists.
If COMAND accesses the Gracenote Media
Database when reading an audio CD, you will
see the following message:
Selecting Gracenote ®
data to be displayed
If the inserted CD does not contain any
Gracenote ®
data, the Gracenote Media
Database menu item is shown in gray and
cannot be selected.

Updating Gracenote ®
music recognition
technology and the Gracenote Media
Database
The digital data on the Gracenote Media
Database becomes obsolete due to the
release of new CDs. Optimum functionality
can only be attained with up-to-date
Gracenote ®
music recognition technology.
Information about new versions can be
obtained from an authorized Mercedes-Benz
Center.
You can have your music recognition
software updated there with a DVD, or you
can update it yourself.
i The Gracenote Media Database is
updated in conjunction with the navigation
system's digital map ( Y page 176).
Setting the audio format
You can only set the audio format in audio
DVD mode. The number of audio formats
available depends on the DVD. The content of
an audio DVD is called an "album", and this
can be divided into up to nine groups. A group
can contain music in different sound qualities
(stereo and multichannel formats, for
example), or bonus tracks. Each group can
contain up to 99 tracks. If an audio DVD only
contains one audio format, the "Group" menu
item(s) cannot be selected.

Playback options
The following options are available to you:
R Normal Track Sequence
The tracks are played in the normal order
(e.g. track 1, 2, 3, etc.).
In MP3 mode, the track order is determined
by the order in which the tracks are written
to the MP3 data carrier when it is created.
Alphabetical order is the most common.
Once all the tracks in a folder have been
played, the tracks in the next folder are
played.
R Medium Mix
All the tracks on the medium are played in
random order (e.g. track 3, 8, 5 etc.).
R Track List Mix (MP3 mode only)
All the tracks that are listed in the current
track list are played in random order.
XTo select options: switch on audio CD/
DVD or MP3 mode ( Y page 210).XSelect CD, DVD-A or MP3 by sliding VÆ and

The "Normal track sequence" option is
automatically selected when you change
the medium you are currently listening to

Multisession CDs
For multisession CDs, the content of the first
session determines how COMAND will
process the CD. COMAND plays only one
session and gives priority to the audio CD
session.
If possible, use COMAND to play only CDs
which have been written in one session.
File structure of a data carrier
When you create a disc with compressed
music files, the tracks can be organized in
folders. A folder may also contain subfolders.
A disc can contain a maximum of 255 folders.
Each folder can contain a maximum of
255 tracks and 255 subfolders.
The disc may contain no more than eight
directory levels. Files beyond the eighth level
will not be recognized by the system.
Track and file names
When you create a disc with compressed
music files, you can assign names to the
tracks and folders.
COMAND uses these names accordingly for
the display. Folders which contain data other
than MP3 or WMA tracks are not displayed by
COMAND.
If MP3 or WMA files are stored in the root
directory itself, the root directory will also be
treated as a folder. COMAND will then show
the name of the root directory as the folder
name.
You must observe the following when
assigning track names:
R track names must have at least 1
character.
R track names must have the extension
"mp3" or "wma".
R there must be a full stop between the track
name and the extension.
Example of a correct track name:
"Track1.mp3".
i COMAND does not support ID3 tags.
Permissible formats
COMAND supports the following formats:
R Microsoft Windows Media Audio V2, V7, V8
and V9 (WMA)
Permissible bit and sampling rates
COMAND supports MP3 files of the following
types:
R fixed and variable bit rates from 32 kbit/s
to 320 kbit/s
R sampling rates of 8 kHz to 48 kHz
COMAND supports WMA files of the
following types:
R fixed bit rates from 5 kbit/s to 384 kbit/s
R sampling rates of 8 kHz to 48 kHz
COMAND does not support WMA files of the
following types:
R DRM (Digital Rights Management)
encrypted files
i Only use tracks with a bit rate of at least
128 kbit/s and a sampling rate of at least
44.1 kHz. Lower rates can cause a
noticeable deterioration in quality. This is
especially the case if you have activated a
surround sound function.Audio217COMANDZ

Notes on copyright
MP3 or WMA tracks that you create or play
back are generally subject to copyright
protection in accordance with the applicable
international and national regulations.
In many countries, reproductions, even for
private use, are not permitted without the
prior consent of the copyright holder.
Make sure that you know about the applicable
copyright regulations and that you comply
with these.
If you own these rights yourself, e.g. for your
own compositions and recordings, or if the
copyright holder has granted you permission,
these restrictions do not apply.
Notes on CDs/DVDs
Discs with copy protection are not
compatible with the audio CD standard and
therefore may not be able to be played by
COMAND.
There may be playback problems when
playing copied discs. There is a wide range of
data carriers, disc-writing software and
writers available. This variety means that
there is no guarantee that the system will be
able to play discs that you have copied
yourself.
There may be playback problems if you play
CDs that you have copied yourself with a
storage capacity of more than 700 MB. CDs
of this type do not conform to the currently
applicable standards.
i On many DVD audio discs, the last track
does not contain any music and COMAND
then switches to the next disc. This is
normal system behavior and does not mean
that there is a malfunction.
! Do not affix stickers or labels to the discs.
They could peel off and damage the drive.
The drive is designed to hold discs which
comply with the EN 60908 standard.
Therefore, you can only use discs with a
maximum thickness of 1.3 mm.If you insert thicker discs, e.g. those that
contain data on both sides (DVD on one
side and audio data on the other), they
cannot be ejected and can damage the
drive.
Do not use discs with a diameter of 8 cm,
even with an adapter. Only use round discs
with a diameter of 12 cm.
i COMAND is able to play back audio CDs
in multichannel audio format.
MUSIC REGISTER
General notes
You can store music files in MP3 or WMA
format in the MUSIC REGISTER. The memory
