I had very bad scratches on my nav screen when I bought the car, basically the screen being cleaned/dusted by hand which had scratched into the anti-glare top coat. After doing a lot of research I came across this post on lumenlab. Seeing as how these guys were nutters and had tested lots of different products, I felt a little bit mroe confident!

So I bought from some Peek Metal Polish from eBay and got to work on my nav screen. I removed the bezel surround from the screen so I could get at the whole screen, this is a good article on how to do that. The alternative is to remove the 4 screws from the side of the screen, and with the ribbon cable still attached, flip the screen round and remove the 4 screws from the back. Attach the screen back onto the unit so it has something to hold it in place while you work on it.

Using small amounts of Peek Polish, I polished the screen in straight strokes (vertically, then horizontally) until all the anti glare coat had been removed. I then used a finer polish, in this case Zymol Cleaner Wax (it's very slightly abrasive). It took about 15 mins in total to fully polish the screen.


Here is the screen before...





And here is the results after...







The screen looks a million times better, and I thought the reflection from the sunlight would be bad (I have a E46 'vert as well) but it is not that bad at all.
