what radio unit do you have as the OEM camera will only work with the nav 600/900
if your head unit is aftermarket you are best using an aftermarket camera
also the oem camera with the green connector is real bad picture you need the one with the gray plug
also a vci code from vauxhall will be needed to get it to work but only if you have rear factory parking sensors
i have just done it myself
