I swapped the standard radio from my Astra for a Sony Bluetooth unit when I got the car.
Now my cousins g/f has a Corsa with a tape player head unit, and I said she could have my old CD player one. Will she need a code for it when she installs it, as I cant remember if I ever needed one, and I don't have any paperwork from the car it came from, so if there is a code, I don't have it any more.
If I do need one, where can I get it from? :\
