I have an 02 ES and was using the stock, 6 disc cd/tape player before I installed a double din. I sold the double din and put the stock back on but it's not letting me play cd's. It doesn't give me the option to load them at all. I don't know if it thinks it's full with 6 cd's or what's going on. I can listen to the radio and mess with everything else but nothing happens when I press any CD related buttons. Anyone have any ideas??

These are on the screen. Not sure if it makes a difference..."6, asl and msg reads"
