First reported in March, it is announced officially now...

When the new telephone module with Bluetooth (SAP-Profile) software from Mercedes-Benz Accessories GmbH is on board the mobile telephone can simply remain in the jacket pocket or handbag. Once registered, the Bluetooth (SAP-Profile)-compatible mobile telephone is recognized by the new system as soon as it comes within range of the vehicle. Due to the SAP-Profile software (SIM Access Profile) the module automatically accesses the SIM card.

In addition, access is also possible to the internal memories of specific mobile telephone models. This means that the user is not only able to telephone, but can also search for a stored number or read a SMS. All these functions can be safely and user-friendly controlled by the driver via the multifunction steering wheel, the audio system and the central display in the instrument cluster. This comfortable feature is an addition to the Mercedes-Benz range of telephone equipment.

A further advantage: compared to standard Bluetooth solutions without SAP-Profile are the best possible reception and the best audible quality inside the vehicle. Thanks to Bluetooth (SAP-Profile) the new telephone module provides the connection to the GSM network via the exterior antenna of the car telephone. This means that the mobile telephone has no connection to the GSM network, access is automatically deactivated and the unit switches to standby mode.

The module has only one button. This activates the 'pairing' process, i.e. the initial connection between the mobile telephone and the module. From then on the connection always functions automatically.

The telephone module with Bluetooth (SAP-Profile) enhances the mobile telephone system in many current Mercedes-Benz vehicles. Because the plug connections are compatible it can be simply plugged into the mobile telephone pre-installation in the centre armrest.
