USB memory stick
To facilitate the use of a USB memory stick,
avoid storing any files other than music files in
the memory. It takes considerably longer for
the system to load storage media that contains
items other than compatible music files.
NOTE
The system supports removable media
which is compatible with USB 2.0 and the
FAT32 file system, and can handle a maxi-
mum of 500 folders and 64,000 files. The
memory must have a capacity of at least
256
Mb.
Optimum sound reproduction
The audio system is calibrated for optimum
sound reproduction by means of digital signal
processing.
This calibration takes into account loudspeak-
ers, amplifiers, passenger compartment
acoustics, listener position etc. for each com-
bination of car model and audio system.
There is a also a dynamic calibration that takes
into account the level set for the volume con-
trol, radio reception and vehicle speed.
The controls that are explained in these oper-
ating instructions, e.g. Bass, Treble and Equal-
izer, are only intended for the user to be able to
adapt the sound reproduction according to
personal taste.
