To reset the BMW e39 radio, you open the hood and test the battery connection. Tighten the positive cable retaining nut and then the negative cable retaining nut. Place the key in the ignition and switch the ignition to the "II" position. Switch the control button on the set. The words "Letter" will show on the BMW radio panel. Enter the code given to you by your BMW dealer using the numbers on the radio header. If you do not have the code, you will need to contact the dealership where you bought the car to request the radio code for your particular BMW.
