Just upgraded to a black Touareg mirror today from the standard auto dimmable mirror.    It's a straight swap and you get to have the ambiental lights shining down on the dash.   Waiting to get dark now and check the effect. will add more pics. Really excited about this because I have the superb cat vision both front and back. The mirror lights should shine down on the dash while the ceiling lights shine down on the gear stick/cupholder area.   Mine came from a 2007
