I have heard that there is a program that can tell you the unlock code for Ford radios. I changed the battery on my girlfriends car and she does not know the code. I called my local dealer who wants £25.......the radio is not even worth that now! The serial number is M134916 and part number 96FP-18K876-EC. Would be much obliged for any help. Thanks.
