Radio on CD6000 not working (CD fine)?

I just purchased a Ford KA with a CD6000 stereo. I just unlocked the CD6000 after a battery swap (Thanks telebumm007) and the CD player works fine but can’t seem to get the radio to make any sound? (no idea if it was broken before)

If I put the volume to 30 (highest volume) I can hear a faint hiss of static but no noise other than that even on a station I know is there, nothing.

I checked the arial cable in the back of the unit and its plugged in.

Any pointers on how to get it to work?
