I've noticed that the mesh shade for my panoramic roof is starting to have quite a bit of tree debris and such accumulating on it from parking the car with the roof left in the vent position. In previous Audis, there was the ability to open the glass but leave the cover closed, making it pretty easy to vacuum off much of what had collected on the mesh. However, I don't really think I can do that in the Volvo since the glass and shade operate on the same switch. Am I maybe missing something? Any ideas?
