How do I disable muting of the radio when reversing?

I'm usually not one for the clichés but if ever one did apply here to this thread I think it would be "first world problems"!

Yes. Well. I do actually live in the 'first world' so I'm not sure what other kind of problems you'd expect me to be experiencing.

To be honest, if I was suffering from malnutrition or cholera from lack of clean drinking water I doubt I'd be on this forum discussing my EV with you fine people.
