Hi all, a quick question for you, I have a lcd top and bottom display on the AMG, the top display, ie compass, audio info etc has an electronic marking on it as if its crystalised under the glass? It doesn't stop you from being able to read the info but it's annoying. I have the opportunity of the dealer putting it right but they have said they can't guarantee that it will be squeak or rattle free when done. Has anyone else had this happen? Or know what it is?
