i
By selecting “LOGIC7
® OFF”, all compatible
formats as they are present on the medium are
played back. Due to the vehicle’s spatial charac-
teristics, an optimal sound experience is not en-
sured on all seats.
i
Please note the following:


For an ideal sound experience at all seats,
the balance and fader should be adjusted to
the center of the passenger compartment
with LOGIC7
® switched on.


The best sound results are achieved by play-
ing high-quality audio CDs and audio DVDs.


For MP3 tracks, the bit rate should be at
least 128kBit/s.


Surround sound does not function for
mono-signal sources.


In the event of poor radio reception quality,
e.g. inside a tunnel, you should switch off
LOGIC7®, as a dynamic switch from Stereo
to Mono could occur, resulting in temporary
sound distortion.


With some stereo recordings, the resulting
sound may deviate from conventional stereo
playback.
i
When you insert an audio CD or audio DVD,
it automatically becomes the active audio
source.

Sirius Satellite Radio provides 100 chan-
nels, so called streams, of digital-quality
radio, among others music, sports, news,
and entertainment free of commercials.
Sirius Satellite Radio uses a fleet of high-power satellites to broadcast 24
hours per day, coast-to-coast, in the con-
tiguous US.
This diverse, satellite-delivered program-
ming is available for a monthly subscrip-
tion fee.
For more information and service availabil-
ity call the Sirius Service Center

next to buildings) or near other technologies. In
such situations, the satellite radio’s main menu
shows the “Acquiring signal...” screen. At this
point, the radio’s functions are restricted to
manual channel number entry (

COMAND audio CD/audio DVD/MP3
means that it is only possible to access the
MP3 tracks. Access to the audio CD tracks
is not possible.
File structure on a disc
When you create an MP3 disc, the MP3
tracks can be organized in folders. A folder
can also contain other folders. A disc can
contain a maximum of 255 folders. Each
folder can contain a maximum of
255 tracks and 255 folders. A disc can
contain a maximum of 4,000 tracks. Usual-
ly this number will not be reached because
each minute of an MP3 track requires ap-
proximately 1 MB of storage space.
Track and folder names
When you create an MP3 disc, you can as-
sign names to the MP3 tracks and folders.
COMAND uses these names for the corre-
sponding display in MP3 mode. Empty fold-
ers or folders which contain data other
than MP3 tracks are not displayed by
COMAND.If MP3 files are saved 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 as-
signing track names:


Track names must have at least one
character.


Track names must have the extension
“mp3”.


There must be a period between the
track name and the extension.
Example of a correct track name:
Track1.mp3
Permissible MP3 formats
COMAND supports the MPEG1 Audio Lay-
er 3 format.Permissible bit and sampling rates


Fixed and variable bit rates up to
320 kbit / s


Sampling rates of 24 kHz – 48 kHz
Notes on copyright
The music tracks that you create for MP3
mode and can play back in MP3 mode are
generally subject to copyright protection in
accordance with the applicable interna-
tional and national regulations.
In many countries, reproductions are not
permitted without the prior consent of the
copyright holder, not even for private use.
Make sure that you know the applicable
copyright regulations and that you comply
with these.
i
COMAND does not support ID3 tags.
i
This format is generally known as “MP3”.
i
Only use MP3 tracks with a bit rate of at
least 128 kbit / s and a sampling rate of at least
44.1 kHz. Smaller rates can cause a noticeable
deterioration in sound quality. This is especially
the case if you have activated a surround sound
function.
