The optionally available COMAND APS control and display system not only guides you to your destination, it entertains you as you go. It features a navigation system with integral radio and CD player. It also lets you 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 optional Harman Kardon® Logic 7® surround sound system provides superb musical enjoyment in your M-Class. With twelve high-performance loudspeakers and the multi-channel stereo 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 innovations like MOST, which improves the sound of poorer recordings, and the 11-channel DSP amplifier make the surround-sound system a genuine highlight and guarantee an incomparable in-vehicle acoustic experience.
