Thread: Video Button

I own a mercedes clk 350 2006 convertible (W209). on my controls i have a button that reads VIDEO. I would like to know if i am able to play videos through inserting a video CD into my CD changer, and if so, what is the format for the videos in order to play it?
this is my first thread thanks for the support.

You see a video you need to install a TV tuner and then some video source.
