i have a 12 disc panasonic cd changer in my nissan (stock), i was wondering if i can still do anything about it not being able to play properly. all i get are these error messages in the head unit. ano kaya yung sira neto? can anyone shed some light? thanks.

there was one time nga, nung pag on ko ng radio, bigla nag eject yung cd case, i know that for a fact kasi pag open ko ng changer luwa na yung cd case.
