Hands free

I have a Hands free kit in a Ford Mondeo ST 220 it's the cradle type and it holds the Sony Ericsson T610. I have no book . The phone works in the car fine. When the phone rings the radio goes off and the radio display becomes the display for the phone. The problem I have is the number of the caller appears but not theres name. do any of you wise guys and girls know how to set it up properly.
