Answer
Ted,
If you do not have the owners book for this vehicle, contact the local dealer for help. On most radios if you enter the code incorrectly several times it will cause the circuit that stores the code to be flashed which will basically make it useless. If this happens the radio will need to be sent out to be reprogrammed.
