Supported MP3 File Formats
The radio will recognize only files with the *.MP3 exten-
sion as MP3 files. Non-MP3 files named with the *.MP3
extension may cause playback problems. The radio is
designed to recognize the file as an invalid MP3 and will
not play the file.
When using the MP3 encoder to compress audio data to
an MP3 file, the bit rate and sampling frequencies in the
following table are supported. In addition, variable bit
rates (VBR) are also supported. The majority of MP3 files
use a 44.1 kHz sampling rate and a 192, 160, 128, 96 or
VBR bit rate.MPEG

Playback of MP3 Files
When a medium containing MP3 data is loaded, the
radio checks all files on the medium. If the medium
contains a lot of folders or files, the radio will take more
time to start playing the MP3 files.
Loading times for playback of MP3 files may be affected
by the following:
•Media - CD-RW media may take longer to load than
CD-R media
•Medium formats - Multisession discs may take longer
to load than non-multisession discs
•Number of files and folders - Loading times will
increase with more files and folders
To increase the speed of disc loading, it is recommended
to use CD-R media and single-session discs. To create a
single-session disc, enable the “Disc at Once” option
before writing to the disc.
Operation Instructions - Auxiliary Mode
The auxiliary (AUX) jack is an audio input jack, which
allows the user to plug in a portable device, such as an

audio system to amplify the source and play through the
vehicle speakers.
Pressing the DISC/AUX button will change the mode to
auxiliary device if the AUX jack is connected.
NOTE: The AUX device must be turned on and the
