Eject Nav DVD - Not working

I have 2006 Pacifica Touring Signature Series. I tried to eject the NAV DVD, but when I hit the eject button, nothing pops out. I have tired to select all possible DVD numbers and then eject, but nothing works. I scanned the manual and the navigation manual, but no help there.

Any help would be greatly appreciated,

Operator error. I had seen posts that the unit was in the rear storage area and even liftedf the carpet and saw the tire jack, but did not notice it was on the left side. Saw a post in another forum and checked again and found it.
