To remedy this, I stopped by the local Wal-Mart store and picked up a set of those collapsible sunshades with the suction cups for $4.97. I bought the smaller ones designed to go in a side window of a car to shade sleeping babies and other sun-sensitive passengers. The shades I found come in a set of two called "Suncutters Side Shade" made by a company called Axius (1-888-99-AXIUS). They are black, screen-like material with metal hoop-frames; rectangular in shape (each measures about 12"x16") and together they fit almost perfectly into the recess in the moon roof with some overlap in the middle. The suction cups even have small metal rings to pull the shades off when you don't need them. They go on easily, come off easily and fold up into a small, round pouch about 6" in diameter. Since the moon roof is tilt only, it is completely operable with the shades installed and the incoming air doesn't disturb them.
