You need to state the radio make and model number as there are some variations.If you look two pages back in the "popularity 7"area,there is a set of instructions I posted for a Philips "car 400".This was a very common radio/cassette player in vauxhalls and may do the job for you.If not,post again with the details and someone will have the info.
go to your nearest Vauxhall company and get a code they'll give you to type into the radio bit. most places can do this for free.
