Hi Sam, if the code is the correct one, keep pressing button 1 untill 5 is displayed, then keep pressing button 2 untill 7 is displayed, then button 3 untill 3 is displayed then button 4 untill 3 is displayed then press button 5 to store the code, If the code is incorrect it will display wait 30, if this happens you will have to remove the radio from the car and find the serial number it should look like M654321 then ask a new question on here with the serial number and you should get the correct code
