I disconnected the Battery on my 94' 540I now the radio does not work it displays "CODE"
I have the code for the radio when I enter the code it always beeps on the last number and the radio does not come on.
It should be a 5 digit code and the radio should start working right after you press the last number. If you miss enter the code 2 or 3 times (?) you must wait at least an hour with the key in position 1 before you try it again. If you do not wait it will just keep beeping at you. If you still can not get it to work replace it with an aftermarket one (mp3 playback and what not). That way if you sell the car you can still keep the good radio.
