Manual and automatic toggling between design variants
The manual changeover between day and night takes place in the main menu line in the "Vehicle" menu item.

If the "Vehicle" menu item is activated, the "System settings" menu item can be selected in the submenu line.
If the "System settings" menu item is activated, the following submenu items are then available:
^ Time
^ Language
^ Voice
^ Linguatronic
^ Services
^ Display
^ Reset

If the "Display" submenu item is activated, the following settings can be selected:
^ Day design
^ Night design
^ Automatic

If the "Day design" setting is activated, the day design is also active at night.
If the "Night design" setting is activated, the night design is also active during the day.
If the "Automatic" setting is activated, the day or night design is set automatically according to the light conditions.

Information flow for automatic design variant toggling
The information as to whether the day or night design is activated is supplied by the rain/light sensor (B38/2).
^ The rain/light sensor measures the light intensity, converts this into a digital value and passes on the signals discretely to the overhead control panel control unit (N70).
^ The overhead control panel control unit reads in the signals and places them on the interior CAN.
^ The central gateway control unit (N93) receives the signals on the interior CAN and places them on the central CAN.
^ The COMAND controller unit (A40/3) reads the signals from the central CAN and actuates the day or night design of the COMAND display (A40/8) accordingly via a Low Voltage Differential Signal (LVDS) interface.
