I have recently bought a 2001 Y reg. 2.0 Mondeo Ghia X (new shape). It is fitted with a 6006E audio system, but the CD player seems to be temperamental. Sometimes a CD plays perfectly, sometimes tracks are played with jumps every few seconds, and sometimes Error code E4 comes up with no CD play at all. I have eliminated the obvious by using the same CD, or trying different ones, but there is no consistency. All CDâ€™s played perfectly in my previous Honda, but maybe this system is very sensitive or faulty. Any help or tips very much appreciated. Thanks.
