General malfunctions

The BMW CD changer is optimized for opera-
tion in the vehicle. It may react more sensitively
to defective CDs than devices intended for sta-
tionary use.
If a CD cannot be played back, first check to
make sure it has been correctly inserted.

Humidity

High humidity can fog the CD or the focusing
lens for the laser beam, temporarily preventing
playback.

Malfunctions with individual CDs

If malfunctions occur only with particular CDs,
this can be due to one of the following causes.

Home-recorded CDs

Malfunction sources in home-recorded CDs
include, for example, inconsistent data origina-
tion and recording processes as well as low
quality or pronounced aging of the blanks used.
Only write on CDs with a marker especially
designed for this purpose.

Damaged CDs

Avoid finger prints, dust, scratches, and mois-
ture.
Store CDs in a sleeve.
Do not expose CDs to temperatures above
122

7/506, high humidity or direct sunlight.

CDs with copy protection

Manufacturers often provide CDs with copy
protection. This can prevent or limit the play-
back of these CDs.
