All you need for convenience telephony is a Mercedes-Benz radio (Audio 20, Audio 50 o4 COMAND), a compatible mobile phone and holder which is connected to the exterior aerial via a fixed interface in the centre console. The functions of your phone can be accessed via the screen - incoming text messages and call lists are also displayed here. The integral Bluetooth™ interface allows for a wireless connection with your compatible mobile telephone. And even if you need to contact someone yourself, you can quite safely and intuitively select the person to call using the control unit.
