Notes
BMW CD players and CD changers are
Class 1 laser products. Do not operate if
the cover is damaged; otherwise, serious eye
injury may result.
Do not use CDs with after-market labels; other-
wise, the labels can loosen as a result of the
heat generated during playback and possibly
cause irreparable damage to the system.
Only use round CDs with a standard diameter of
4.7 in/12 cm and do not play CDs with adapters,
e.g. single CDs; otherwise, the CDs or adapters
may jam and it may not be possible to eject
them.
Do not use a combined CD/DVD, e.g. DVD
otherwise, the CD/DVD can jam and will no
longer eject.<

If a CD can not be played, first check if the CD is
properly inserted.
Humidity
If there is high humidity, the CD or the focusing
lens for the laser beam may fog up, making it
temporarily impossible to play the CD.
Malfunctions with individual CDs
If there are malfunctions with individual CDs,
then they may be due to the following causes.
CDs that you burned yourself
Potential problems with home-burned CDs are,
for example, inconsistent data generation and
burning processes, as well as low quality or
excessive aging of the blanks that are used.
Only write on the upper surface of CDs with a
writing instrument that is suitable for the pur-
pose.
Damaged CDs
Avoid leaving fingerprints, as well as dust,
scratches or moisture on the CDs/DVDs.
Store CDs in sleeves.
Do not expose CDs to a temperature greater
than 50 6/122 7, elevated humidity, or direct
sunlight.
CDs with copy protection
CDs are often provided with copy protection
from the manufacturer. This can result in CDs
not playing or playing back in only a limited
fashion.
