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.
Streaming audio via Bluetooth *
General
If the car is equipped with Bluetooth hands-
free* and a mobile phone is connected then the
audio system can wirelessly play back stream-
ing audio files from the mobile phone. Naviga-
tion and control of the sound can be carried out
via the centre console buttons or via the steer-
ing wheel keypad*. In some mobile phones it is
also possible to change tracks from the phone.
To be able to play back the audio a device must
first be paired and connected to the car. For
information about pairing and connection, see
page 263. BT must also be selected as audio
source, see page 238.

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.
