SOURCE: There are 4 or 5

If it were my car first i would get out the owners manual look up the fuses in the index. find the fuses that control the audio system. remove them for a few minutes until the radio loses its reserve power. then reinstall them and let the radio go through its "reboot". This has worked for me before. itf that doesnt work then the top plate piece of your cd player should come off with a small screw driver set. from there you should be able to see the cd s. Im not familiar with how to get that radio unit out of that particular car sorry but its a GM so it shouldnt be too bad.
