I searched quick and couldn't really find anything on a manual eject button. Flip through the manual a little bit and see what it has about the radio. If all else fails and you aren't worried about possibly breaking the stock cd player, some skinny needle nose pliers should reach in far enough to grip the cd and you can pull it out. But there is a good chance you could break the cd player in doing so.

Read the car manual, in the page were it shows the dashboard fuse panel find the radio fuse pull it out and put it back in with the fuse tool. This resets your radio, it did the trick for me with.
Just make sure if you disable the radio security lock if it enabled before you pull the fuse. It may lock you out, all the information is in the manual.
Good luck and hope this helps.

You will have to access a 6 digit code out of the radio Theftlock system then still go to a dealership to get the 4 digit code that unlocks the radio. Most people put in a radio code (4 digits) when new then forget it years later when the battery is replaced or radio removed. Press preset buttons #2 & #3 at the same time with the key in run position and radio on. A 3 digit code should be displayed (write it down) then immediately press the AM/FM button, another 3 digit code will appear. Take the 6 digit code to a GM dealer. They will call Delcotronics with the generic 6 digit code and get you the master unlock code for your radio. You can dial it in using the scan buttons (best to ask the dealer how, or get them to do it). Once set you can change it again or write down the master unlock code and keep it somewhere for the next time the battery is disconnected. If you can't access the 6 digit code, you will still need to bring it to a dealership and have it unlocked by reprogramming it. It actually is a module on the data line and can create trouble codes and be programmed. It can not be taken from your truck and used in any other vehicle unless programmed to that vehicle.
