Have just bought a JVC headunit off ebay so will arrive in a couple of days. As far as i know the sony one in my car is the original HU with the disc changer in the boot (cars a'96 mk3 16v). Dont really know much about stereo stuff, what i am wondering is will the jvc just plug in using the same connections? or will i need adapters? I have only replaced the sony one because one of the buttons fell off and i want one with a ipod lead
