Using a mobile phone by the car driver while driving is not allowed in some countries. One of the

possible solutions is to use a handsfree audiosystem for controlling an inserted and connected mobile

phone.

Such a handsfree audiosystem with steeringwheel-buttons, microphones and loudspeakers and/or

speechrecognition has been developed for easy covering all information and communication needs of

the car users, e.g. listening to radiobroadcasts or calling to a telephone partner.

The central part of the system, the so-called “Head-Unit”, is mounted in the car dash-board as the

basic control unit for information and communication. Via the integrated display and keys it informs

and enables the user to select a radiostation or to use the mobile phone.

Adapters, so-called cradles, adapt selected mobile phones from the market mechanically and

electrically for easy use in conjunction with the control base (head-unit) via a fixed interface plug.

The cradle is attached directly to the Bluetooth Phone Connector (BT-PSC) by this interface plug-in

connector on top of the BT-PSC. The cradle adapts audio communication and data communication

signals to the BT-PSC. These signal informations will be transferred between BT-PSC and head-unit

via a wireless Bluetooth link.

Additionally the interface plug on the BT-PSC has mechanically implemented a coax-plug with no

electrical connection to the BT-PSC circuits. The coax-plug is connected to the external roof antenna

via a separated coax-cable.

BT-PSC will be assembled during the car manufacturing process. Installation will be done by

specialized personnel of the car-manufacturer only.

BT-PSC is not intended to be assembled by the end-user.

Therefore “usage” of BT-PSC will be described in the user manual of the car-informationsystem as

part of that system.

Installation and operation is described in a separate Operational Description document.
