Multi-session disc formats are supported by the radio.
Multi-session discs may contain combinations of normal
CD audio tracks and computer files (including MP3 files).
Discs created with an option such as keep disc open after
writing are most likely multi-session discs. The use of
multi-session for CD audio or MP3 playback may result in
longer disc loading times.
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.

supported by the radios.
Playlist files are not supported. MP3 Pro files are not
supported.
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.
