ok ... LMAO .... are you serious ? if the eject motor or mechanism is broken, is a sawzall or cutting wheel the only way to remove my CDs ?
Is there a FAQ with pictures somewhere on how to cut your CDs out of a dead Mazda head unit ?
I would assume that you could remove the changer then unscrew the covers and then work the mechanism manually somehow or remove the blockage to release the CD's.
If you do need to cut something a grinder or rotary tool would be a better option.
