Hi I have a Sony CDX-415RF. I just got another changer on ebay b/c my other one stopped working and there is power to the changer but it will not allow me to select for the Cd player through the source button, I have tried hitting the reset button on the face, is there a reset button on the changer as well? I need help!!!All the other functions work, ie the tape deck and radio...please help. Oh and there is no info anywhere on this changer that I could fine.
