Audio Systems: cd changer, radio connections, broken radio

Question
I have 2001 sebring.  My radio was broken.  The cd changer lights would flash still; 1 and 2 then 3 and 4 always flashing back and forth even though my radio did not work.  Just replaced radio and its works fine but separate cd changer seems to be dead; no lights even flashing. HELP PLEASE

Answer
The flashing could be the changer attempting to reset itself or perhaps it was getting "mixed messages" from the broken radio.  If you now get no action at all, I would first check the wiring harness to be sure that the new radio connections are compatible with the changer.
