CD player suddenly mute

[Simpo Two]

2011 XF, standard audio. For 9 months I've used a CD with MP3s on it and it's worked perfectly. Now suddenly, although I can see the seconds going up as it plays, there's no sound. Radio is fine.

Is this related to the false 'low screen wash' and 'park brake fault' warnings that have been going on for the last month or two?

After burning another MP3 CD but getting exactly the same result, I finally found the answer.

'Turn the unit off and then back on again'.

I'll live with the continuous 'screen wash low' warning as my main dealer is better at coffee than cars.

Love tech.
