TMC Navigation Traffic info. become useless

Thanks m-a8.
I found that something has gone wrong with FM Radio, so that is probably why TMC has all but disappeared. I don't listen to radio apart from on the way to work, and that is on DAB. FM, DAB, MW & LW work fine but FM hardly works, so will have to toubleshoot that when I get time.

Fixed it. Yet again it was radio frequency interference - this time from a chinese USB media player I installed in the media rack to put video into the defunct analogue TV. It did not affect DAB at all, just FM. I think I will live without it rather than try and mitigate it. Thanks for all the advice and corroboration.
