Radio stations have disappeared on Ford digital radio

[DetailMouse]

The built in radio, had digital stations listed and you could choose them using the voice controls when I got it. All of a sudden both methods have disappeared and I'm restricted to the station I'm currently listening to.

Does something need resetting? How?

Thank you

Someone's probably stolen your aerial. Happened to me. New one was £20 from citroen in my case

Ah, it made me look, but no, the aerial's still there
