Brief Description Of Components
The following components deliver signals for the digital compass:
- Magnetic field sensor
- up to 09/2006
The magnetic field sensor is installed in the mirror base. The magnetic field sensor measures the current alignment of the magnetic field. The signal is sent to the control electronics for the compass in the interior mirror.
- from 09/2006
The magnetic field sensor is on the PCB in the interior mirror.
- Control electronics for the compass
The interior mirror is electrically connected to the roof control panel (FZD).
The control electronics for the compass are integrated into the board for the interior mirror. The signals from the magnetic field sensor are received by the control electronics. The LCD display is activated directly by the control electronics.
The following components are controlled:
- Display in interior mirror
- up to 09/2006
The LC display (window) is situated at top right in the interior mirror.
The points of the compass are presented digitally on the LCD display (LCD: Liquid Crystal Display). The display is divided into eight compass points.
- from 09/2006
The point of the compass is displayed in transparent light technology in the interior mirror as well. The display is also at the top right in the interior mirror. The display is divided into eight compass points.
