I have an opel and just put in the code.
1. Switch on the ignition.
2.Turn off the radio.
3. Press the AS button and hold down.
4. Switch on the radio and hold down the AS button until you hear a loud beep.
5. The word "Code"will appear and the # of attempts you have left to try. Usually "10" _ _ _ _ .
6. Enter the code using the 1 2 3 4 buttons. You do that by pressing the 1 button until the first # you need appears. For example you press the 1 button once and 0 appears, twice and 1 appears. Once you reach the first # go to the 2 button and keep going. After you enter the code press the AS button again and the beep should be heard. Good luck.
Cheers, Jon
