MP3/WMA mode
You can also use this car sound system to
play CD-Rs and CD-RWs that contain MP3
music fi les. You can also play WMA fi les.
This chapters deals only with playing
MP3 fi les since the operation for MP3
and WMA fi les is identical.
Notes:
WMA fi les with Digital Rights
Management (DRM) from online mu-
sic shops cannot be played with this
device.
WMA fi les can only be played back safe-
ly if they were created with Windows
Media Player version 8 or later.
Preparing an MP3 CD
The various combinations of CD burners, CD
burning software and CD blanks may lead to
problems arising with the device’s ability to
play certain CDs. If problems occur with your
own burned CDs, you should try another
brand of CD blank or choose another colour
of CD blank. To avoid problems when playing
self-burned CDs, you should not burn CDs at
speeds greater than 16-speed.
The format of the CD must be ISO 9660
Level 1/Level 2 or Joliet. Other formats can-
not be played reliably.
When creating (coding) MP3/WMA fi les
from audio fi les, you should use bit rates
from 32 to 320 kbit/s for MP3 fi les or 32 to
192 kbps for WMA fi les.
