My Dad has a 57 plate XJ8 It was British imported to Japan and imported back again. The sat nav works but the radio only picks up 73-84 FM and the phone doesn’t work as in it won’t connect to a mobile. I have been advised that there might be an amplifier on the radio to search that small band width but to restore it, it will need the CCF reconfiguring. Is this something that you could help with?>
