2004 A6 2.7T Quattro sedan:

Is there a rear mesh sun shade that was made for this model or one that would fit properly? I had a manual version in my 2002 Passat, and loved it. I understand that the hot weather package on this model had an electric version, but I would prefer a simple installation... has anyone installed anything like this? Or has anyone even seen one; maybe from a used parts dealer?
