Nakamichi MB-70 6-disc In-dash Musicbank CD Changer
The product advertised here and showing in the picture is the MB 70. It is not a stand alone item. It needs to be controlled by another Nakamichi product, but Nakamichi people did not know which product is compatible with it.  The MB 75, on the other hand, is a stand alone product that does not need any other to control it. It is a radio and 6-CD changer all-in-one.  I ordered this item and reveived the MB 70. It took me some time before realizing the problem. I ended up returning it.
