Citroen C3 original head unit stereo playing up

[jxde-xox]

Hi, I bought a Citroen C3 (2002 model) the other day, and everything was working fine

However, a couple of days after I bought it, the radio stopped working?

It’s displaying ‘MHZ’ and then a frequency (radio station number) - but nothing is playing and no matter what is pressed it isn’t playing anything. It’s still playing CDs absolutely fine though!

Any help is greatly appreciated, Thankyou

I suspect this is still related to the Head Unit issue in your other post.

Can you confirm you have replaced the original RD4 Head Unit into the vehicle and performed the reset I posted?
