Well having replaced the CD changer with a 2nd hand one sort of off Ebay, I went to put a couple of extra CDs into the magazine, and it won't eject, and the HU reports no magazine. I can see one of the trays is extended.
I tried unplugging it and plugging it back in, but no luck. It whirrs a bit when I try to eject it, but doesn't eject.
Does anyone know anyway to fix this, short of dismantling it?
