Does anyone know where I could buy a 12 disc changer for a 1997 Toyota Avalon XLS?

My disc changer is dying and I'm looking for a new one. I've been looking around and I can't find a 12 disc changer that is compatible with my radio. Every disc changer I find is compatible with the 1998 model, but I can't find anything for a 1997 model. If possible I'd like to just buy a compatible disc changer for a decent price. I don't want one that I can tune my radio into because I've heard that the quality of sound isn't good at all. I've been searching for a long time so if anyone has any idea please let me know.
