Notes
BMW CD/DVD players and changers are
officially designated Class 1 laser prod-
ucts. Do not operate if the cover is damaged,
otherwise severe eye damage can result.
Do not use self-recorded CDs/DVDs with labels
applied as these can become detached during
playback due to heat buildup and can cause
irreparable damage to the device.
Only use round CDs/DVDs with a standard
diameter of 4.7 in/12 cm and do not play CDs/
DVDs with an adapter, e.g. CD singles, as other-
wise the CD/DVD or the adapter can jam and
may no longer eject properly.
Do not use a combined CD/DVD, e.g. DVD
Plus ,
otherwise the CD/DVD can jam and will no
longer eject.

General malfunctions
BMW CD/DVD changers and players have been
optimized for performance in vehicles. In some
instances they may be more sensitive to faulty
CDs/DVDs than stationary devices would be.
If a CD/DVD cannot be played, first check
whether it has been inserted correctly.
Humidity
High levels of humidity can lead to condensa-
tion on the CD/DVD or the laser's scan lens and
temporarily prevent playback.
Malfunctions with individual CDs/DVDs
If malfunctions occur only with particular CDs/
DVDs, this can be due to one of the following
causes.
Self-recorded CDs/DVDs
Possible reasons for malfunctions with self-
recorded CDs/DVDs are, e.g., inconsistent
data-creation or recording processes, or poor
quality or high age of the CD/DVD blank.
Only label CDs/DVDs on the upper side with a
pen intended for this purpose.
Damaged CDs/DVDs
Avoid fingerprints, dust, scratches and mois-
ture.
Store CDs/DVDs in a sleeve.
Do not subject CDs/DVDs to temperatures over
122
7/506, high levels of humidity or direct
sunlight.
CDs/DVDs with copy protection
CDs/DVDs are often provided with a copy pro-
tection feature by the manufacturer. This can
mean that some CDs/DVDs cannot be played or
can only be played to a limited extent.
Care
If necessary, clean the reflective scanning side
of the CDs/DVDs with a commercially available
cleaning cloth by wiping in straight lines from
the center outward.
