. #1. I have an 2016 A3 Sline. Two weeks ago the DAB waveband disappeared from the radio. My DAB channels are still showing under my saved channels but when I select them there is no sound. If I turn up the volume it says that the channel is unavailable. I’d tried all settings and a reset but cannot resolve it. . #8. So, it turns out that something changed with the recent update. It is no longer sufficient to just turn on the traffic mode in the maps (in fact it might not even be necessary to do that at all). There is now MMI Content options for traffic. Once I turned those on I get traffic on my normal view and in the Google Earth view too. rZayY.
