KA Radio fading out
My KA is now 5 years old and I have not had a problem with the radio until recently. When I am listening to an FM station, after a few minutes, the station fades to static and won't come back for the rest of the journey. I can still receive MW, and I have checked that my aerial is still there and ok! When this first started, it would fade after driving for approx. 40 mins. Now, it starts to fade after 10 minutes.
Can anyone help me please?
