Gracenote

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

Switching to CD audio mode
(

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

mum of nine groups. A group may contain,
for example, music of different sound qual-
ities (stereo and multi-channel formats) or

tremely variable. It is possible that a device con-
nected as an external audio source will sound
quieter or louder in the vehicle or that the usual
maximum volume cannot be achieved. On cer-
tain devices the volume can be set separately. In
this case, start at a moderate volume and in-
crease it slowly. In this way, you can determine
whether the system is capable of playback with-
out distortion, even at high volume.
