Audio Systems: How to remove disks from unpowered changer, screw driver, plastic tab

Question
I have an out-of-the-dash Matsushita Model 86201SA110 6-Disk CD changer with 6 disks still in it.  Without power, how can I eject the disks.

This is a curved-front unit from a 2006 Subaru.

If I have to apply power, which pins get the ground and +12-Volts?

Thanks

Answer
SOME CD CHANGER HAVE A HOLE ON THE METAL CASE SOME OTHERS YOU NEED TO open the case  ealry 95 will have it
under the cd changer or back, there is a plastic tap with a spring  you can push that plastic tab and the magazine will eject
use a small screw driver
