Ford KA Radio code help?

Hi all, I recently had to remove the battery from my ford ka and now my radio display is locked. The radio make is 6000cd.

I've searched across the site and *think* that I have my radio serial number (I held the 6 button and pressed 1 and a list of numbers were displayed).

So the serial number is M050802 I think, is there anyone here that can help provide me with the radio unlock code?

Thanks in advance
