Code needed 6000CD RDS EON?

I have bought a Ford Focus with a radio 6000CD RDS E.O.N. from auction, and the code is being asked for. Model is 6000CD.EON Serial M765558 Part no. YS4F-18C815-AA. This car was from N.Ireland and I have not a contact with owners. The code given in the book was wrong. If somebody help me with this problem. Thanks in advance.
