I'd go back to the dealer with my tools and a hammer as a back up and say, "let me try"
I did find out last night while installing some lights, when you disconnect your battery it will eject what ever is in the radio. I had a CD and a Tape in my stock unit and after I plugged every thing back up I noticed they were both sticking out. Whether they came out when I disconnected or reconnected I don't know. But since your was broken to begin with it probably didn't
