12 disc changer wont read the cd's....push the cd button and just get the ERR sign. it happened out of no where, on my way to school it worked, then leaving school it happened. id like to fix it myself but i have no clue what could be wrong.

 

I went through hell and back to replace mine with the original used ones on ebay but all i had to do was buy a cassette adapter 5.00 and plug in my MP3 player and presto, great sounding music at a fraction of the cost, just remember to put the stereo on tape.
