Don't give up! I had the SAME problem and was able to get the CD with a little help. The plastic faceplate is no big deal; it's just there for show (if it's the one I'm thinking of).
Here's my post from a while back that may help if you get it working again:
Messed Up Nav System after Upgrade to 24_1 OS
But more importantly, here's how to take the CD out. This is for a MKIV system, but the procedure is the same. Original post at:
http://www.bimmerboard.com/forums/posts/117017/; I also attached the 3 methods mentioned in the post at the end.
Good luck!

o buy another MkIV but a search on Google with some key words turned up an extremely useful thread here that details three ways of removing a stuck CD/DVD (third message up from the bottom of the page):
http://www.bmwportal.net/modules.php...r=asc&start=15
I already had the computer out and in bits so I used method 3, which is as follows:
1) With the computer out of the car, remove the top cover (prise it up with a screwdriver),
2) With the DVD slot towards you, remove the T-7 Torx srew holding the motor at the rear right of the drive.
3) Move the motor to the right to expose the plastic gear underneath.
4) Turn the plastic gear anticlockwise to operate the mechanism to unload the CD.
5) Replace the motor (no need to wind the gearing back) and replace the top cover.
As is so often the case, it's easy when you know how.
NOTE that this requires breaking of the paper seal on the cover, which will VOID THE WARRANTY if there is one.
After putting the MkIV back in the car I left the nav DVD out, not wanting to get it stuck again. Obviously the nav wasn't working without the nav DVD in but everything else was working OK. And yes, the Info and Select buttons were working!!
It seems that even though the v21 installation prior to the DVD getting stuck had appeared to go wrong, it had still installed correctly.
I was still reluctant to put the nav DVD back in with v21 installed in case it got stuck again. With navigation selected the "Please insert CD/DVD" prompt was on the screen, so I switched off the radio and went through the v26 installation, including the radio steps as per Brian's procedure and everything went smoothly.
Success! Everything is now working, including the Nav and Select buttons. So if it hasn't been proved before, Brian's procedure does work with the BM24 TMC.
Interestingly, when the Info and Select buttons were not working the radio stations scrolled down the left hand side of the screen only, even on v26. Now they appear in two columns, which makes better use of the full screen.
Thanks a bunch for all your help on this guys. It is very much appreciated!!

I wouldn't worry about it. At least you know you can fix it with a better copy after you get the pesty disc out. Here's a post from Ard in another message board:
"Here are some methods i've gleaned elsewhere-
Method 1:
I had one stuck in mine and remembered what I had read on the BMWNAV forum that someone else had said. I shut the car off locked the doors and walked away for a few minutes to let it spin down, I returned, unlocked the trunk with the key and hit the eject button. It came out. I did this twice. The second time I had to go through the procedure two times but it worked.
Method 2:
What you need to do is remove the power connector (wait until the power light id OFF), wait a few seconds, replace the power connector and HOLD the eject button in until the disc comes out.
It took about four or five tries, but that is what the BMW service info says to do and it worked. Give it a couple of minutes each try of holding down eject.
Method 3:If holding the eject button in for a long time doesn't work then your going to have to manually remove the disk. Take the nav computer out of the car and remove the top cover. When the cover is removed you can see the loading mechanism drive motor near the top right hand side of the unit (with the disk loading slot towards you)Use a T-7 Torx screwdriver to remove the screw holding the motor in place. The motor will just move to the right hand side, no need to disconnect any cables. Beneath the motor is a plastic gear, rotating the gear will operate the loading mechanism and assuming nothing else is broken in there, your CD should come out. When you put the motor back, be sure to place it as far left as possible in order to make sure that it mates correctly with the gear.
NOTE: Damaging the 'tamper proof' seal WILL void the warranty (if there is one). A heat gun is an excellent way to soften the adhesive and remove all sorts of tamper labels...
