The optionally available new COMAND APS control and display system with a high-resolution 6 1/2-inch colour display and hard disc navigation not only guides you to your destination with 3-D maps in bird-eye’s view, showing altitude, points of the compass and steering wheel angle, it entertains you as you go, too. It features a navigation system with integral digital radio and CD player. It also enables you to operate the optional sound system, the CD changer and the telephone. A TV tuner for analogue and digital TV reception is available as an option in combination with COMAND APS.

The navigation system works with the Global Positioning System (GPS) and a hard disc on which the European road network is stored. An additional service offered in Germany and some other European countries is dynamic route guidance, which uses traffic information provided by radio stations to guide you around traffic jams/tailbacks where there is an alternative route.

The multimedia systems of the new M-Class generation are anything but distant fantasies. Starting with the DVD video function. The media interface with UCI connection allows you to connect an MP3 player directly to the optional sound system. And if you have stored your favourite music on a MUSIC REGISTER card, with its 4-GB capacity, or on an SD card, you will find the matching socket in the M-Class. For safe and convenient phoning with the mobile telephone, there is a Bluetooth hands-free system.

Radio, navigation device and telephone obey your every word – you can operate them with the LINGUATRONIC voice-operated control system.

The optional new Harman Kardon® Logic 7® surround sound system provides superb musical enjoyment in your M-Class. With its output, increased to 510 Watts it brings excellent sound quality to your M-Class. With twelve high-performance loudspeakers and Dolby® Digital 5.1 technology you have got your very own concert hall, wherever you are sitting. Added to which you have the sort of functions you won’t find at a live concert. For example, you can set the surround reproduction individually – either just in the front, middle or rear sections, or for the entire passenger compartment.
High-tech developments such as MOST, a new interface for external audio devices and storage media as well as the 11-channel DSP amplifiers turn the surround sound system into a veritable highlight and provide an unforgettable feast for your ears inside the vehicle.
