CD changer General malfunctions The BMW CD changer is optimized for operation in the vehicle. It may react more sensitively to defective CDs than devices intended for stationary 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 origination 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 moisture. Store CDs in a sleeve. Do not expose CDs to temperatures above 1227/50 6, high humidity or direct sunlight. CDs with copy protection Manufacturers often provide CDs with copy protection. This can prevent or limit the playback of these CDs.
