2003 Envoy "Check CD"

I have a 2003 envoy with a single disk/cassette player. The CD player recently stopped working and reads "Check CD" for any CD (original, CD-R, etc.) that I put in. It acts like it is reading the CD then gives the error message and spits the CD out. Any suggestions or help would be much appreciated!

I have the same truck and just started experiencing the same problem last week. I can't seem to find any info. Let me know if you've had any luck.
Thanks

Try disconnecting the neg battery terminal for 3 mins.
