Mercedes Black Leather Headrest Monitors from w221/s550

My headrest were connected using a ground-,power+ and video input. These function like any other "aftermarket" headrest. Only these are genuine mercedes s class headrest with the curved headrest poles. You would néed a video source. Like a dvd player. I used my iPhone. I was able to connect the video to the headrest and the audio using this coolstream device through the factory aux Imput
It's not very simple to install anything on these mercedes but its possible.
