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 CD’s played perfectly in my previous Honda, but maybe this system is very sensitive or faulty. Any help or tips very much appreciated. Thanks.
