Does anyone know if the wiring for a boot-mounted CD changer is fitted as standard in a Golf Mk4 - it's a GT TDi 130 if that makes any difference. I'm not sure how to go about digging around behind the First-Aid compartment and boot trim to try and find it - any tips?

Also if anyone has a mounting cage for the standard changer that they want to sell then let me know... And a long cable to hook it up if I can't find one there already!
