What is this little window??

I was putting a bike rack on my wagon today and noticed that the front piece of roof (the black part between the windshield and the sunroof) is not metal like I thought but actually glass. That's not the mystery though. What I noticed was that there is a tiny "window" in the middle of that panel. I took some pics and my apologies that it is so hard to see. Inside the window is what looks like two louvers of some sort made out of a shiny black polymer of some sort. Have any of you ever noticed this before? What is it??

Yes, for ventilation in hot weather so instead of burning to death when your car sits in the sun, you just get boiled. Slightly less painful

I looked at the parts catalog for the car and although I see a rectangle marked on that particular panel there are no other specific parts mentioned, so it must be an integrated part of that roof piece.

I stopped by my dealer today and had the mechanic come out and look at it to see if he could tell me what it was and even he was stumped! He had never noticed it before either. In fairness you have to stand on the door jamb and look down onto the top of the roof in order to be able to see it. He is going to ask around and see if he can find out what it is.

Is this your guess or are you certain? It doesn't look like a solar panel at all.
