Updating Gracenote ® music
recognition technology and the

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.

updated in conjunction with the navigation
system's digital map (

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.
