Hey fellas on my 91 740 the radio doesnt work. It has a EEE on the screen and I cant do anything with it. The guy I bought the car from had the radio in the trunk because he said it didnt work with the code he had. I plugged it back up and it asked for the code, I typed the code he gave me in and it went to EEE so I assumed it was bad. I finally got the correct code from the dealership but I cant get the radio to stop saying EEE. I have tried unplugging it and everything but nothign works. The second time I got the radio to ask for the code was by unplugging the fuse but that no longer works. What should I do?
