I have recently fitted a pioneer avh-x7800bt and I have a cd in the unit that does not eject when I press the button. It does play ok. There is no hole to stick a pin like on a CD-ROM drive.

Disc Eject Prohibit: This feature keeps the disc from ejecting even if the eject button is pushed. The disc eject prohibit feature is engaged/disengaged by pressing the CD and Eject buttons simultaneously for more than 2 seconds.

Turn it off so you see the "demo" screen or the blank "off" screen, then hold eject + volume (mute) button down for few seconds to turn the eject lock off.

You can assist the face in going all the way down, once it is in this position it will automatically eject the cd. When the face starts to come down simply help it/gently force it to go the entire way with your hand, mine has the same issue and this is what I do everytime and it seems to work fine.
