Audio System: Introduction: Notes

On previous vehicle models, the radio was always controlled by an integrated control unit. This control unit included the tuner, cassette deck, amplifier, display and the operating unit.

The radio could be equipped as an Hi-Fi audio system by adding further components (CD changer) or boosters (Digital Signal Processor etc.). Because of the increasing number of functions in a radio and the limited area available in the standard radio chassis, new solutions had to be found for the radio control unit.

In the E65, the radio control unit is no longer in a single module. The audio system has distributed functions which are integrated in various control units, e.g. the display and operating function.

The radio is operated via the Controller in the center console, the display is produced in the Control Display located in the instrument panel and the audio signals are controlled in the ASK.

There are two audio systems available for the E65 from the start of production: A basic Hi-Fi and the optional LOGIC 7 Hi-fi.
