I installed some subs today and i had to take the headunit out to hook up the line converter. I was really careful not to move it around or bang it on anything when i removed it. When i put it back in, the radio works but the cd function does not. it won't eject or load. when i hold in the eject botton it says, "cd eject all". whats goin on. it seems like its just one of those stupid easy fixes, cause i dont think its broken.
