radio problem

The radio went off on it's own. Came up with CODE message. Don't know the code. What to do to make radio work?

you need the code... it is some times in you owners manual, if not you will have to call a BMW dealer, and give them the ser.# off the back of the radio.. If you put the wrong code in, you will have to wait one hour with the key on before you could try again...

he is right, call dealer and provide the ser#, they will give you a code. simple as that.
