An additional base plate and cradle is available for specific cellular telephones, available as an option. It provides charging of the cellular telephone and a connection to the outside antenna. All cellular telephone interaction and data transmission to mobile telephone control module is done via Bluetooth. In order to create a connection between the mobile telephone control module and the infotainment system, the mobile telephone control module must be switched on and the cellular telephone logged in. The mobile telephone control module switches itself on and off via the ignition. If the ignition is switched off the mobile telephone control module can be switched on and off via the infotainment system. When a telephone connection is active, the radio sound is switched off. When the telephone connection has ended, the radio sound is switched on again.
Speech recognition
The speech recognition enables the operation of some cellular telephone functions by voice input. It recognizes commands and sequences of numbers independently of the person speaking. The commands and sequences of numbers can be spoken without a break between the individual words. It is also possible to save telephone numbers using a name randomly chosen by the user. The telephone connection can be created using the proper name.
