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 build-up 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. Single-CDs, other-
wise the CDs or the adapter can jam and will no
longer eject.
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 if 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 only occur with individual CDs/
DVDs, one of the following factors may be the
cause.
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 top, with a pen
designed for this purpose.
Damage
Avoid leaving fingerprints, as well as dust,
scratches or moisture on the CDs/DVDs.
Keep CDs/DVDs in protective sleeves or cases.
Do not subject CDs/DVDs to temperatures over
50
6, high levels of humidity or direct sunlight.
CDs/DVDs with copy protection
CDs/DVDs are often copy-protected by the
manufacturer. This can mean that some CDs/
DVDs cannot be played or can only be played to
a limited extent.
