sorry not a vectra c sorry, but i plan to remove the sony head unit I fitted when I bought the car and put back OM one! but when i fitted the new one I got the stealers to change the display to show the date where the radio stuff was displayed, if i remember right he set it to no radio, as the display was blank, so would i need to get it changed back or will it see the radio and change by itself?

thanks Ronnie
