Radio Code Required

Hi , my radio was disconnected (Nissan Micra 2003) and now it's asking for a code. I have the manual, which came with a 'radiopass' sticker with the following details -

BP2347 - Model
32038190 - Serial No
4438 - Safety No
28 185 AX610 - Part No (I think)

Can anyone help provide the code to unlock?
