MERCEDES-BENZ SL-CLASS ROADSTER 2013 Owners Manual

There is a version of
Gracenote® music recognition technology,
Emeryville, California, USA on the
COMAND
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 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.

Audio
COMAND

selection window. See the example of the
display in audio CD mode
(Y
page 425).
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 Random Medium
All the tracks on the medium are played in
random order (e.g. track 3, 8, 5 etc.).
R Random Track List (MP3 mode only)
You hear the tracks of the current track list
or the currently active folder (including all
subfolders) in random order.
i The Normal Track Sequence option is
automatically selected when you change
the disc you are currently listening to or
when you select a different medium. If an
option is selected, it remains selected after
COMAND is switched on or off.
Notes on MP3 mode General notes
Depending on the volume and format of the
MP3 data, the length of time required for
reading the data may increase.
Permissible data carriers
R
CD-R and CD-RW
R DVD-R and DVD-RW
R DVD+R and DVD+RW
R SD memory card
R USB storage device Permissible file systems
R
ISO 9660/Joliet standard for CDs
R UDF for audio and video DVDs
R FAT16 or FAT32 for SD memory cards and
USB storage media
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
that 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.
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 that 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 one
character.
R track names must have the extension
"mp3" or "wma".
R there must be a dot between the track
name and the extension.
Example of a correct track name:
"Track1.mp3". Audio

COMAND Z

Permissible formats
COMAND supports the following formats:
R
MPEG1 Audio Layer 3 (MP3)
R Microsoft Windows
Media Audio V8 and V9
(WMA) without copy protection
Microsoft Windows Media Audio V2, V7, V8
and V9 (WMA)
R additional music files in AAC format with
the file extensions .aac, .mp4, .m4a
and .m4b, but not copy-protected iTunes
music files with the extension .m4p.
i If, in addition to MP3 files, there are other
music files in these audio formats stored on
the disc, the loading process may require a
longer time before the first track is played.
i The MP3 audio encoding method is under
license from Fraunhofer IIS (Institut
Integrierte Schaltungen – Institute for
Integrated Circuits) and Thomson.
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
R variable bit rate
R WMA Pro
R 5.1 Surround
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. 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
! COMAND is designed to play discs that
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
device.
Only use round discs with a diameter of
12 cm. Do not use discs with a diameter of
8 cm, even with an adapter.
Discs with copy protection are not
compatible with the audio CD standard and
therefore may not be able to be played by
COMAND.
Playback problems may occur 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. If COMAND 432
Audio
COMAND

therefore switches to the next disc, it is
normal
system
behavior and does not mean
that there is a malfunction.
i COMAND is able to play back audio CDs
in multichannel audio format. Music search
