locked radio

[Clayton]

after years with the car last week i inadvertantly let the battery run down, i had a funny feeling at the time that this would bring consequences. last night the wife says "you know the radio dont work" i thought straight away its coded, which it is. it is the factory fitted unit with 6 stack cd player, now i have all the paperwork but cant find the code. to make matters worse the wife has pushed that many buttons the thing has gone to help mode and locked. anyone have any ideas before it goes to the main dealer for a wallet massage.
