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 breaking 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 several entries exist for the CD of a
particular artist, you can select which of the
entries should be shown.
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.
iThe Gracenote Media Database is
updated in conjunction with the navigation
system's digital map (Y page 173).
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 multi-channel 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.
XSwitch on audio DVD mode (Y page 205).XSelect DVD-A by sliding VÆ and turning
