Design of the Central Information Display

Design of the central information display
The central information display (CID) includes the following components: advanced TFT display, crossed coil motor and mounting with switches.
^ Advanced TFT display
The LC display is designed as a 6.5 advanced TFT display. The display is of identical design as the 6.5 display of the on-board monitor in the E46. The advanced TFT display adapts automatically to the brightness of the ambient light. The display has a visible range of 144 mm x 79.5 mm and a resolution of 400 x 240 Pixels. The display is an analogue unit and is controlled by RGB signals.
The display is mounted such that it can rotate and is moved by a crossed coil motor.
^ Crossed coil motor with gear mechanism (Stepper Motor)
The crossed-coil motor is a brushless DC motor. The positions of the display are detected by Hall sensors on the gear mechanism.
^ Mounting
The display and the crossed coil motor are accommodated in a mounting. The mounting is located in the center of the instrument panel so that the same component can be used for left hand drive and righthand drive vehicles. The mounting is screwed flush with the surface of the instrument panel.
^ Switch
Left and right switches are integrated in the trough. The left switches serves the purpose of finely setting the display to improve the readability corresponding to the seat position and light conditions. The right switch serves to fold the display in and out.
When raised, the position is between 35-108 degrees. The position last stored (last function memory position) is raised. The display can now be finely adjusted in steps (1 step = 1.2 degrees) using the left hand switch. The signal from the switch is sent directly to the stepper motor and is not transferred via the Kbus.
Manual fine adjustment of the display is also possible in a range from 35-108 degrees. In an area below this range (< 35 degrees), the CID is closed automatically as it can no longer be read effectively in this position. The righthand switch can be used to close the display.
Navigation directions are not interrupted if the display is closed while the navigation system is active. When terminal R is switched off, the CID is always closed and the last position stored. The display can be switched off by means of a button in the main menu.








If the display is closed manually or electrically while driving, the display will remain closed at the start of the next trip (last function memory position). The display must first be raised again by pressing the switch.
