Stereo not turning off/on with ignition.

Stupid problem but recently my 172 stereo has stopped turning on and off with the ignition. It's the standard head unit so anyone know if this is just a setting that I've turned off?

Clocks/cig lighter still working? Could be a fuse

Had this in one of ours. 15A radio fuse.

Just checked and cig lighter isn't working so fuse has gone. Thanks guys.
