Radio module disconnected ??

[rogerco]

About a month ago the screen started showing "Radio Module Disconnected" and playing loud white noise when turned on. I can still select bluetooth music which works ok. I never use the radio but its a bit annoying. Does anyone know how to fix this? System reset makes no difference and the message implies a physical problem (eg plug fallen out). Where is the radio module and its connections?

And the answer is...

... disconnect the 12 volt battery, count slowly to 20, and reconnect it.
All came good.
ie turn it off and turn it on again at a deeper lebel. ?‍?‍?
