Anti-theft audio system
General information
Some models are equipped with an audio system having an anti-theft feature that will render the stereo inoperative if stolen. If the power source to the stereo is cut, the stereo won’t work even if the power source is immediately re-connected. If your vehicle is equipped with this anti-theft system, do not disconnect the battery or remove the stereo unless you have the individual code number for the stereo.
Refer to the owner’s handbook supplied General information

Unlocking procedure
1 Turn on the radio. The word “CODE” should appear on the display.
2 Using the station preset selector buttons, enter the five-digit code. If you make a mistake when entering the code, continue the five-digit sequence anyway. If you hear a “beep,” however, stop immediately and
start the sequence over again. Note: You have three attempts to enter the correct code. If the correct code isn’t entered in three tries, you’ll have to wait one hour, with the radio on, before you enter the codes again.
5 Once the code has been entered correctly, the word “CODE” should disappear from the display, and the radio should play (you’ll have to tune-in and enter your preset stations, however).
6 If you have lost your code number, contact a BMW dealer service department.
