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

-
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.

(including missed calls) during phone opera-
tion in separate lists. Call lists are not availa- ble unless a mobile phone is connected with
Audio 20.
Audio 20 supports the PBAP Bluetooth
®

file. For this reason, note that the system
behavior differs, especially when telephoning
via the Bluetooth ®
interface:
R Bluetooth ®

The call lists are downloaded automatically
by Audio 20 as soon as the mobile phone
is connected to Audio 20.
R Bluetooth ®

The call lists are generated and displayed
by Audio 20.
You can deactivate the automatic download
function for contacts and call lists stored in
the phone (Y page 55).
If you have activated the "Hide data" function,
Audio 20 does not display the call lists
(Y page 55).
i Bluetooth ®

Audio 20 are not synchronous with the call
lists of your mobile phone. These calls may
or may not be listed on your mobile phone,
depending on the model.
