Audio and Telematics
The audio system will only play audio files
with ".wma, .aac, .flac, .ogg and .mp3" file
extensions and with a bit rate of between
32 Kbps and 320 Kbps.
It also supports VBR (Variable Bit Rate) mode.
No other type of file (.mp4, etc.) can be played.
".wma" files must be of the standard wma 9 type.
The sampling rates supported are 32, 44 and
48 KHz. In order to be able to play a recorded CDR or
CDRW, when recording it is preferable to select
the ISO 9660 level 1, 2 or Joliet standard.
If the disc is recorded in another format it may
not be played correctly.
It is recommended that the same recording
standard is always used for an individual disc,
with as low a speed as possible (4x maximum)
for optimum sound quality.
In the particular case of a multi-session CD, the
Joliet standard is recommended.
It is advisable to restrict file names to
20 characters, without using of special
characters (e.g. " " ? ; ù) to avoid any playing
and displaying problems.
