Hello, my name is***** you for allowing me to assist you today. Your question may take more that one post to get an accurate answer.
First make sure that you have at least 10 Volts to the connector on the unit. Then check the software version that you are using. It should be 4.0, if not update it and see if the unit will work.
If neither of these work, do a soft reset on the unit and see if that will clear the error.
