Multi-Information Display (MID)

Multi-Information Display (MID)












Both the 528i and 540i will use the MID for control and display of the radio/tape/CD changer and clock

If installed, the Digital Sound Processor (DSP) will also be adjusted and controlled through the MID.

Additionally, in the 540i, the MID will also be used as the control and display for the Board computer and telephone.

Operation of the MID corresponds to the MID in the E38. It does not perform any calculations, it is only an input/display device.

As with the E38, the E39 MID contains two sets of displays

Main Display - A 32 character display for presentation of primary information.

Menu Display - 6 small display blocks above each button switch for labeling the switch functions.

Menu Buttons - the buttons are designed as rocker switches having a left and right side contact. The function of each button changes as the different systems are selected.

Selector Buttons - These buttons are used to select the desired system to be used (540i only):







- Audio - calls up the radio/tape/CD control functions for operation and programming.
- Telephone - used to program and call up stored telephone numbers.
- Time/BC - calls up the clock and BC control functions for programming and display.

Search Button -

The integrated "m" button is used to switch over to a "manual" search of the functions listed above. An "m" is posted in the display when in this mode. The "m" button is also used to activate the radio test.
