The magazine on my 6 disc changer won't eject. Has anybody ran into this problem? Also, can I just purchase a new Panasonic changer and basically plug and play? Or do I need some adaptor wiring for the Bose System? Prestige said I can trade the core in for a new one for about $240 but I'm not sure if this is the best price. Any info on this would be much appreciated, thanks.
