on the interior display i got an "ERR" display and it wouldn't play the cds. i tried looking for an answer but i never have any luck.

any suggestions. at first i couldn't get the 6pack out, now after a day it popped out. i'm afraid to put it back in again. please any help is greatly appreciated.

 

there are a ton of threads on here addressing this, you haven't searched very hard, nor read the FAQ

 

Try turning the cds around. In other words the side with the music faces up.
