General

One of the design parameters of the E38 was to create a mare tranquil interior.

The objectives were:
- Reduce the number of control buttons
- Easier operation
- Displays that are easier to understand
- More precise information
- Higher visibility of text
- High Quality appearance

These objectives are achieved with the new multi-information display (MID) for the E38.

The new MID incorporates the controls for the audio system, telephone and on board computer Since the same format is being used to control each of these systems, operation is more convenient.

The MID doesn't perform any calculations. It is an input request/display unit using signals to and from the IKE.












The MID is designed with two displays

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

- Menu Display - 6 small displays for labeling the button functions.

- Menu buttons - The buttons are designed as rover switches having a left side 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:
- Audio - calls up radio, tape, and CD control for operation and programming functions.
- Telephone - used to program and call up phone numbers.
- Time/BC - calls up clock and BC function for programming and display.

- Search Button -
- Radio - Will activate search for radio stations in either up or down scale directions.
- Tape - activates music search in forward or reverse tape direction.
- CD - activates title search up or down the title list.

- Volume control
- Push button that turns the audio system on and off.
- Rotary knob that controls the volume of the audio system and telephone hands free speakers.

- Status Led
- LEDs that are red, yellow, green for signaling the status of the telephone.
- A red fan symbol that signals to status of parked car ventilation.

Because of the increase in size of the main display, information from more than one system can be displayed at the same time i.e. radio station and time.
