just finished cleaning my car and noticed on the MMI screen the following marks. Anyone know what these are. Used a clean microfibre cloth. There was a tiny rough dot in the centre of the marks. After cleaning that area it's left the marks you can see on the screen. It cant be seen at alltimes but at the right angle it is very visible. It's like the coating of the screen has come away. Anyone know if you can actually replace the screen itself.
