code for philips radio in FIAT car

[dam1]

Hi,

I did the classic change of battery and now i'm left with the radio asking for the code which of course i don't have!
Really need it now cause i have to sell the car.
Please tell me if you can help, here is the info i have:
Model no: 22DC449/64S
PROD NO: FD 0298048020705;

Thank you very much

Damien
