The procedure is a little complicated,but here goes! 1/. Drive your car to the local town centre2/.Remove radio from car and place down the back of your trousers.3/.Stand in the middle of the High Street and revolve six times anti-clockwise while whistling " Dixie". The code should now be restored,if it isn't you will have been arrested for public disorder and won't need the radio while you're in prison anyway ! Good luck with this,let me know how you get on. best wishes from your favourite B-in law.
