how do i put in a radio code for a n reg astra help!!!?

1) Switch on the ignition.
2) Press and hold the AS button and switch on the radio. The display will show "SAFE" after 3 seconds it shows "10_ _ _ _"
3)Enter the code from your radio passport with the preset buttons 1,2,3,4
EG. If the code is 3650
Press preset button 1 3 times 10 3 _ _ _ _
press button 2 6 times 10 3 6 _ _
press button 3 5 times 10 3 6 5 _
press button 4 10 times 10 3 6 5 0
Press AS button until a bleep is heard and the radio starts operating.
If you enter the wrong code the display will show "SAFE" and after the waiting time 9 _ _ _ _ now enter the correct code as you only have 9 chances left before you lock the stereo out!
