Hi, new to the forum and hopefully posting in the correct place. I have a 2015 A6 Black edition with MMI plus. I have always had a traffic overlay on the sat nav showing roads in red when traffic was heavy and green when light. For some reason, the overlay no longer displays. I have traffic switch on and I do see traffic in the list, just not as an overlay on the map. My traffic account is active until end of October so no issue there. It would be great if anyone could advise... Thanks in advance.
