Stream mp3 code, octavia mk2 2005

I just purchased a stream mp3 head unit on ebay without a code and have been looking online and seen that most likely when i will plug the new head unit into my car i will be asked for a code ( not supplied)

Just wondering if i supply the cd player serial number could someone generate me a code before my item turns up because the last thing i wont to do is fork another £20 on ebay for a code

+ i bought the mp3 as mine only has a stream and will be adding an aux
