Have you checked there is no water in the spare wheel well.

It might be worth a battery reset

The problem is most likely the BM24 radio module - I have had several and found them unreliable - they suffer from dry joints on the circuit boards - this leads to audio dropping out and unresponsive controls, including not being able to switch the radio off.

I had exactly the problem you describe and tried everything. Eventually bit the bullet and upgraded to BM54 and problem went away.

You could of course put the original Rover unit back in to check that I am right. I have a spare if you need one, and a couple of working BM24 units as well.
