My father-in-law is doing up an old Clio, but the radio is locked out and he doesn't have the code. If someone could help, it would be very much appreciated. Numbers on the side of the radio are as follows: Model No: 22DC278/62B T0V842 RN278F20187712 Prod No: FD0202170187712 Barcode: 8200057681TV842 8200 057 681 --B
