Problems with 2004 S-500

I recently bought a S-500 and it's been in the shop several times in the first three weeks.
The steering wheel convienence motor/module failed and it wouldn't work
and both were replaced.
The V60I phone was defective and was replaced.
The voice module was replaced and that one was replaced with an
updated one.
The CD changer was replaced as it would freeze.
The radio froze up once on FM.

Finally here is the latest situation..

The vehicle only has 650 miles on it.

First the device unavailable statement came up when I went to use the CD changer. I went to eject the cassette and it won't eject leaving me to believe a CD is stuck inside or the device has failed.

This is the second changer as the first one was defective. Needless to say it's going back to the dealer service on Monday .

Is it possible for me to release the CD cassette without remnoving the changer?


Thanks.[
