I searched in the how-to section but could not find it. My wife likes to leave the sunroof tilted open in the summer to vent the heat build-up inside the CX-9. Problem is that over the past seven years, dirt, small leaves and pine needles have deposited on the sunshade. I can see them when I am drying the roof of the CX-9, but cannot get my vacuum attachments in to vacuum it all up. Is there a way of detaching the sunshade from the sunroof so that I can safely open the sunroof with the sunshade closed?
