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].)
