You need to enter the security code. If it's the original radio the code will be printed on your "Car Pass". This is about the size of a credit card and has the radio, immobiliser and key codes on it. Look through the handbook pack and any paperwork you got with the car.
If you cant find it you can get a copy from a Vauxhall dealer, they used to cost about £25.
