universal trick for ejecting a CD mag: take a credit card, and "pop" it underneath the mag, like you are swiping the card at a gas pump. 90% of the time that will eject the mag. If it doesn't you have a CD stuck halfway in and halfway out. if that is the case, you need to open the changer cover, and manuual rotate the gears to slide it back into place.
