it worked. 2 discs must have been put in one slot because one of the disc at the bottom was offset, didn't realize these things were so intricate inside. Use your 6 disc CD changers with care!
and as a side note those screws are not hex screws, there star shaped screws used to prevent stripping. I managed to get them off intact with a vice wrench, then pulled the discs out of the front of the device.
