You will need to extract radio (may need tools - cost about �1.50 fron car accessories shop) and quote the number on the radio. Plenty of help here as I have found.
hi
once you get the radio out have a look along the side of the radio and you will see the serial number. it will start with the letter M,L,C or A followed by 6 numbers e.g. M123456
once you have this number, post it on here and i will give you the code. good luck and take care
