switch on ignition and switch radio on by pressing volume knob the display then shows SAFE
Now switch off the radio by pressing volume knob be sure to leave ignition on
press and hold the AS button with the AS button still held switch radio on by pressing volume button keep AS pressed until you hear a confirmation beep the display will then show CODE and the number of remaining attempts you have to enter correct code maximum of 10.
Now by using preset buttons 1,2,3 and 4 you can enter your code for example if the code is 0365 press preset button 1 once to display a zero then press preset button 2 four times to display a 3 preset button 3 seven times to display a 6 and preset button 4 six times to display a 5.When you have entered the correct code press and hold AS button for approx 3 seconds until you hear a confirmation beep and that all there is to it.Hope that helps.
