Usage ........................................ 155General information
The Infotainment system's CD player
can play audio CDs and MP3/WMA
CDs.
Important informationCaution
Under no circumstances place
single-CDs with a diameter of 8 cm
or shaped CDs in the audio player.
You must not put any stickers on
CDs. These discs can get jammed
in the CD drive and ruin the player.
Replacement of the device will
then be necessary.
■ The following CD formats can be used:
CD-ROM Mode 1 and Mode 2.
CD-ROM XA Mode 2, Form 1 and
Form 2.
■ The following file formats can be used:
ISO 9660 Level 1, Level 2 (Romeo,
Joliet).
MP3 and WMA files written in any format other than listed above may
not play correctly and their file
names and folder names may not
be displayed correctly.
■ Audio CDs with copy protection, which are not in compliance with
the audio CD standard, may not
play correctly or not at all.
■ Self-recorded CD-Rs and CD-RWs
are more vulnerable to mishandling
than prerecorded CDs. Correct
handling, especially in the case of
self-recorded CD-Rs and CD-RWs, must be ensured (see below).
■ Self-recorded CD-Rs and CD-RWs
may not play correctly or not at all.
In such cases it is not the
equipment that is at fault.
■ On mixed mode CDs (audio tracks and compressed files, e.g. MP3,
are stored), the audio tracks part
and the compressed files part can
be played separately.
■ Avoid leaving fingerprints when you
change CDs.
