I have a Grundig 200 radio in my Corsa (1999) and I called Vauxhall a few months ago to retreive the code which they did give me over the phone, the battery was faulty and now I dont have the code they have said that they dont have it on record anymore as the car is old

Does anyone have the code for this radio ?

I would be so grateful if someone could help me and thank you :-)
