The head unit will just shut off. I have check all the fuses, wires, grounds and connections and every thing appears to be in order. I replaced both batts. thinking that might be the problem but no. The radio will shut off on cd, tuner, sat radio, i pod at any vol. level. What could it be??? Please help
