Radio Tuner problem

[sloss]

The Radio loses signal and mutes, the screen shows a speaker symbol with a line through it. Used to be occasional but it's very frequent now.

If I select anything else, ie CD or Nav then go back to radio it will probably work for a while again. DAB, FM, Med and Long Wave are all affected.

I've done the simple things like break and re-make the connections on the Kenwood Unit but that's all so far.

CD and TV all work fine. Is it the same aerial for them all?

Does the Panel have any ideas?
