CDs with the vehicle at a standstill and
operate the audio system only if permitted
by road, weather and traffic conditions.

Multi session CDs
With multisession CDs, the content of the
first session determines how COMAND
treats the CD.
For example, if the first session contains
data in audio CD format and the second
session contains data in MP3 format,
COMAND will treat the CD as a
conventional audio CD.

i
CDs, software and hardware for writing
audio data to CDs vary widely.
Therefore, we cannot guarantee that
COMAND will be able to play every
user-written CD. Problems may also be
encountered during playback of user-
written CDs with a storage capacity of
more than 700 MB.
