How do I removed Discs from a 2003 Jeep Liberty 6 Disc Player?

I have a 2003 Jeep Liberty 6 Disc Player/Radio. The radio works fine. The Player will not return any of the 6 discs. All the Discs are factory made and have no labels attached to get caught. The Player occassionly makes noise, but most of the time it does not. The Players also does not show the 6 locations all the time. I have removed the unit from the vehicle but cannot figure how to open it and retrieve the CD Discs.

Any suggestions.
