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. CD singles; 
otherwise, the CDs or the adapter might jam 
and 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.

<

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.

High levels of humidity can lead to condensa-
tion on the CD/DVD or the laser's scan lens and 
temporarily prevent playback.

If malfunctions occur only with particular CDs/
DVDs, this may be due to one of the following 
reasons.

Possible reasons for malfunctions with self-
recorded CDs/DVDs are, for example, inconsis-
tent data-creation or recording processes, or 
poor quality or old age of the CD/DVD blank.
Only label CDs/DVDs on the top, with a pen 
designed for this purpose.

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 
above 122

7/506, nor to high humidity levels 

or direct sunlight.

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.
