Query: Does not work with CD changer shown

This JD-612V magazine does not work with the PD-M426 Pioneer 6 disc changer they suggest purchasing it with. I read the reviews on this magazine after recieving it and it appears to be for a car player. Waste of money and I don't have time to send it back. There is a 3 pack offered with what appears to be the correct magazine (M300KP)for the PD-M426 so I'll keep my fingers crossed. The picture looks the same as the one that came with the machine. First time Amazon has let me down.
