KDC-MP543U CD Player.SIR, I am Arunjames, in my car this player is used to be precise something happened to the system automatically its not playing,while trying manually also, but if we are pressing in the small recover button using a pen or pencil it will play for about 30-33 minutes only after that it will automatically turn-off for starting it again we had to press the same button via pen/pencil. so i think some installation probs caused ..is it so...i Hope u will give a satisfied reply. Thanks...
