Had the Frau pick me up one of these. I like it. Takes 2 set screws to remove. TUV approved with Cert.

Thank you Herrk!

Actually it seems to be the rear window of the car; that goes up only (I think so) when the roof is closing and not a deflector.
The deflector on the F12 looks like the one on the Z4 made in fabric.

And the whole system is pretty big and complex:

But I am waiting for your pics when you would have done it!
