I got a latest Audi Navigation DVD 2016 for my 2006 A8L MMI 2G from Ebay. As all my original disc, always use ImgBurn to create an ISO file from it. Burn it to a blank DVD with the lowest speed possible and verify option to make sure the burn was GOOD. If the verify passed then the burnt DVD is GOOD to use. I think the best is to have MMI 2G software updated to 4610.
