Please can anybody help me with regards to my wifes stereo setup in her mondeo. It has a 5000 series tape player with the ford 6 cd changer fitted. It has never given trouble until this week when she selects cd mode it will flash up ERROR on screen and revert to radio later on she would try and it would work fine. Its not working at all now though it says ERROR E2. To determine whether it was a cd changer problem or radio problem i fitted my 6000CD head unit and it was still the same however now flashing up ERROR E5? Can anybody help? If anyone has a manual with the fault codes in id be grateful for help. Thanks
