I have the Bose system in my A6. I noticed the screen is missing some color, if that makes sense. When is says the song or radio station 2 of the lines of light are out. Any one know how to fix this or do I just have to deal with it. I have the same problem on the screen on my dash(where the speedometer and everything is).

 

Unfortunately you'll have to live with it. The information box in the gauge panel does this and there's no way of fixing the problem unless you purchase a new one from the dealer. Everyone has this problem and it's annoying. This goes the same for the deck but at least that's cheaper then the gauge cluster.
There's been other posts regarding this problem, you should find them and read them to get a better understanding of this pixelation. It deals with the pixels going bad due to weather and wear.
