1. switch on ignition - not necessary to start car!!
2. Press AND HOLD "AS" button
3. Whilst STILL PRESSING "AS" button turn radio on
4. Wait till beep is heard
5. Should then show "----" on screen - release "AS" button and enter code as normal
i,VE DONE ALL OF THIS & EVEN DISCONECTED THE CAR BATTERY TO SEE IF THIS RESETS THE RADIO STILL STUCK ON SAFE CAN ANY ONE HELP
