Hello, After a lot of phaffing around I have finally got my concert to MMI 3G high retrofit installed and running. The last thing I needed to do was to get a different screen surround for the new 7inch HD screen. As I was struggling to find an A4 version on eBay I decided to splash out on a new one from Audi at £43. I explained what I had done and the guy said the part number was: 8K2857185DR66 (the R66 is the flex metallic trim type) I'm sure that is the 6.5inch one and I need 8K2857185HR66. Can anyone confirm which part number is correct??? Cheers, Lee.
