eurovox cd stacker in vr statesman

[statesman05]

I have just bought a VR statesman and it had a kenwood single cd H/U. I have put the original eurovox unit back in and found that under the console was a wired eurovox cd changer control. Can anyone tell me if this is tandard and it mean't the car had a eurovox stacker in origonally ? Also, the H/U came with the eurovox stacker cable, can anyone tell me the origonal route the cable took fromk the H/U to the boot and where in the boot the stacker was mounted. All help would be appreiciated.
