When I fire up the NavNet TZT2 system the auto pilot display used to fire up with the entire system, now the auto pilot display has no power and I am getting a constant beep on the navnet network screen that "nav pilot position source changed" and it is a constant beep and reminder. We are also getting the "HDG source changed. Need Calibration" but we still have no power to the auto pilot head unit. We have checked fuses, connections, terminals etc and still have no power to the head unit, is it possible the head unit is bad and is causing these errors or is it possible the processor is bad?? Any ideas or suggestions? Thanks so much. Also getting the "speed Source changed" error on the TZT2 display screen.
