     3So our OpenBM device should be able to work inside of the original 16:9 bord monitor housing. For this we would like to know how all the buttons work there. 
     4Here is an image showing those both original pcb on which the buttons and LEDs are installed (klick on image for full size).

     8The connection to the main board is done through one 12pin and one 20pin connector. The connector is some kind of special ALPINA connector, at least I wasn't able to find such one anywhere. So, we will need them in order to connect our board with the button board. Here is an image, how this buttons do looks like (this image is taken from Bengt-Olof Swing, who works on a similar project, see [http://www.mp3car.com/vbulletin/hardware-development/139907-button-interface-bordmonitor-bmw-e39-e46.html here].)
