[StCassel]

I thought that I was lightly dusting off my navi screen but, a couple of scratches have been made. Very light scratches, which are visible only under specific lighting conditions. The scratches can not be felt. The presence of the scratches are an annoyance when sunlight hits the navi screen just right. Does anybody know how these scratches could be eliminated? Can the navi screen be replaced without replacing the whole factory-installed navi unit?
