We have a B250 with the panoramic (dual?) Sun roof. The front part has a shade and opens up. The rear doesn’t seem to have a shade. Is that exprected?

 

My car also has the dual panoramic sun roof, and front glass opens by tilt, and also by moving back.
it has electric shades that deploy from centre between the 2 pieces of glass in unison.
it also has a blackout solid shade, deployed by hand, from rear of rearmost glass.
hope this helps!

 

Cancel last sentence, no solid blackout shade, that is other car, sorry for confusion
