My '91 XJS has a CD boot changer which is not being activated by the tape/Cd button on the stereo, neither is the CD holder ejecting from the changer. Any advice please?

Hi,

Assuming the head unit and boot CD device are original and have both been verified as functional, then that would suggest;

• The DIN cable plug is loose either behind the head unit or the boot CD device

• The DIN cable is compromised - maybe damaged at some point between the header unit and the boot CD device

If the head unit and/or boot CD device are not original then its possible that the boot CD device is not compatible with the head unit. I mention this as my '94 XJ40 required a completely different boot CD device compared to my old '96 X300 XJ6. Both cars had identical looking Alpine head units although I'm led to believe that there are differences - I needed to replace my '94 alpine head unit as the power supply had failed; rare as rocking horse poo! My XJS has a non-standard Sony single disc head unit.

If you have your VIN to hand, the Jaguar Classic Parts website will help identify the correct variants.
