WARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is cov-
ering a distance of 44 feet (approximately
14 m) every second.
If you make a call on your mobile phone while
driving, always use hands-free mode. Only
use the mobile phone when road, weather
and traffic conditions permit. Introduction
Audio 20, in conjunction with a Bluetooth ®
-
capable mobile phone, enables you to make
calls via the Bluetooth ®
interface. Using the
Bluetooth ®
interface and a suitable mobile
phone, you can use the Audio 20 hands-free
facility and receive vCards.
With a suitable mobile phone, you can use the
hands-free system via the Bluetooth ®
inter-
face. You can also import contacts from the
mobile phone via PBAP (Phone Book Access
Profile) and receive vCards.
You can obtain more detailed information
about suitable mobile phones and about con- necting Bluetooth
®
-capable mobile phones
from your authorized Mercedes-Benz Center.
You can also obtain information via the Inter-
net at http://www.mbusa-mobile.com (for
customers in the USA only). Call disconnection while the vehicle is
in motion
A call may be disconnected if:
R there is insufficient network coverage in
certain areas.
R you move from one transmitter/receiver
area (cell) into another and no channels are
free.
R you use a SIM card which is not compatible
with the network available.
R you are using a mobile phone with "Twin-
card" and the mobile phone with the sec-
ond SIM card is already logged into the net-
work. Operating options

for a 911emergency call:
R the mobile phone must be switched on.
R a network must be available.
R a valid and operational SIM card must be
inserted in the mobile phone.
R the mobile phone must be connected to

®
inter-
face Prerequisites
To use Bluetooth ®
interface telephony in con-
junction with Audio 20, you need a Blue-
tooth ®
-capable mobile phone.
On Audio 20
X Activate the Bluetooth ®
function on
Audio 20 (Y page 33).
On the mobile phone
X Switch on the mobile phone and enter the
PIN when prompted to do so (see the
mobile phone operating instructions).
X Activate Bluetooth ®
functions and, where
necessary, Bluetooth ®
visibility on the
mobile phone (see the mobile phone oper-
ating instructions).
The battery of the mobile phone should
always be kept sufficiently charged in order
to prevent malfunctions.
In preparation for telephoning via the Blue-
tooth ®
interface, you should check the fol-
lowing items on your mobile phone (see the
mobile phone operating instructions):
R Hands-Free Profile
The mobile phone must support Hands-
Free Profile 1.0 or above.
R Bluetooth ®
visibility
On some mobile phones, it is not enough to
activate only the Bluetooth ®
function. Your
device must also be made "visible" to other
devices (see the mobile phone operating
instructions).
This visibility is for restricted periods of
time on some mobile phones.
R Bluetooth ®
device name
Every Bluetooth ®
device has its own Blue-
tooth ®
device name. This device name is
freely definable, but can be identical for all
devices from the same manufacturer. It is
therefore recommended that you change
this name so that you can easily recognize Telephony via the Bluetooth

Depending on the volume and format of
the MP3 data, the length of time required
for reading the data may increase.
Permissible data carriers R
CD-R and CD-RW
R USB storage device
Permissible file systems R
ISO 9660/Joliet standard for CDs
R FAT16 or FAT32 for USB storage media
Multisession CDs For multisession CDs, the content of the first
session determines how Audio 20 will proc-
ess the CD. Audio 20 plays only one session
and gives priority to the audio CD session.
If possible, use Audio 20 to play only CDs that
have been written in one session.
File structure of a data carrier When you create a disc with compressed
music files, the tracks can be organized in
folders. A folder may also contain subfolders.
A disc can contain a maximum of 255 folders.
Each folder can contain a maximum of
255 tracks and 255 subfolders. A maximum
of 512 files are permitted on an MP3 CD.
The disc may contain no more than eight
directory levels. Files beyond the eighth level
will not be recognized by the system.
Track and file names Audio 20 does not support ID3 tags. Music
files can contain meta information such as
artist, album or track names. Audio 20 dis-
plays this information during playback.
When you create a disc with compressed
music files, you can assign names to the tracks and folders. Audio 20 displays these
names if no meta information is available.
If MP3 or WMA files are stored in the root
directory itself, the root directory will also be
treated as a folder. Audio 20 will then show
the name of the root directory as the folder
name.
You must observe the following when assign-
ing track names:
R track names must have at least one char-
acter.
R track names must have the extension
"mp3" or "wma".
R there must be a dot between the track
name and the extension.
Example of a correct track name:
"Track1.mp3".
Permissible formats Audio 20 supports the following formats:
R
MPEG1 Audio Layer 3 (MP3)
R Microsoft Windows Media Audio V2, V7, V8
and V9 (WMA)
R music files in AAC format with the aac and
m4a extension, but not copy-protected
iTunes music files with the extension m4p.
i If a disc contains other files in addition to
music files, the loading time is longer.
i The MP3 audio encoding method is under
license from Fraunhofer IIS (Institut Integ-
rierte Schaltungen – Institute for Integrated
Circuits) and Thomson.
Permissible bit and sampling rates Audio 20 supports the following types of
MP3
files:
R fixed and variable bit rates from 32 kbit/s
to 320 kbit/s
R sampling rates of 8 kHz to 48 kHz Audio CD and MP3 mode
