I have just purchased a new cd player for the car but cannot get it to work, think I have a problem with the wiring. The player is a Sony CDX-GT30RN I looked on the sony site for wiring instruction but no luck. The radio cassette that came with the car is working well but just thought I would update to the 21st century with a CD player but having no luck. The plugs on the back of the old unit seem to fit ok but think I must be doing something wrong - any ideas?
Thanks
