Operating unit

IRIS (integrated radio and information system)

The IRIS operating unit contains the operating and display elements for:

• Radio functions
  
• Clock functions
  

The push-button information on the IRIS is transferred in the form of an I-bus/K-bus telegram to the relevant control unit:

• IRIS radio operation to radio set
  
• IRIS clock operation to basic instrument cluster / IKE
  

In turn, these control units send text information via the I-bus/K-bus which is then shown in the IRIS display.

MID (multi-information display)

The MID is used as soon as further optional extras in addition to the functions which can be operated by the IRIS are installed in the vehicle.

Depending on the scope of equipment, the MID contains the operating and display elements for:

• Radio functions
  
• Clock functions
  
• On-board computer functions
  
• Telephone functions
  
• DSP functions
  

The components are linked via the I-bus/K-bus. The push-button information on the MID is transferred in the form of an I-bus/K-bus telegram to the relevant control unit. In turn, the control unit sends text information via the I-bus/K-bus which is then shown in the MID display.
