2010 Ford Fiesta Titanium Diesel Radio Trouble?

This has only started happening today, it seemed to happen after an issue occurred with syncing my iPhone using Bluetooth to the radio.
The car no longer turns the radio off after turning the ignition off, I have to press the off button myself after returning on the ignition. When the radio has finally gone off and I have left the car, the display no longer goes off after locking the car it still displays the time and date at fu brightness.
Any help or advice?

Push the off button and hold it in for four seconds.
