A penny fell into the disc area on our cd player radio. How do I get the radio out to get the penny out?

You don't specify what type of chevrolet you have but i'll try to help you as most of them have same procedure pry the molding that goes around gently whit a screw driver if you have another tool that is more flat like a long spatula or else starting from any end or corner and moving toward the other end it will snap off it clips to the actual dash and if this have any electric buttons or devices attached unplug then you will see the 4 screws that hold the radio take them off and unplug radio to instal just reverse procedure and snap the trim on by pushing or taping please let me know if this helped or give more details of your car if you need more info i'll be happy to assist you.
