I killed mine.
I pulled the fuse on mine after having the Pano Glass open on its own while driving down the hwy one morning. It took 6 attempts to get it to close tightly. Now I am stuck with the interior cover open approx 1 inch.
I never opened the thing ever other than when I detail the car.

What marketing person thought that having 5 feet of sliding glass with folding options was a good idea?

Mark me down as a pano roof hater......
