210 Audio X X 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: Switch on audio CD mode (Y page 205). Select CD by sliding VÆ and turning cVd the COMAND controller and press W to confirm. X Select Gracenote Media Database by turning cVd the COMAND controller and press W to confirm.

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. COMAND i The 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. X Switch on audio DVD mode (Y page 205).
