Garmin 430 VLOC fault
Hi guys,
I came accross a fault on G430, so I was wondering has anyone ever experienced something similar...
VLOC side of G430 is paired with panel mounted course deviation indicator and it used to work like a charm. When all of a sudden it decided not to work anymore. The owner says, that they did nothing to it that would result in this situation. He even had some avionics people taking a look at the wiring/hardware side of it and they found nothing wrong.
I believe it's software problem, but not sure, as yesterday I switched it ON and it actually went through the self test once (needles half up/half right, no flags), but upon restarting went back being U/S.
Also, as he bought the airplane a few years ago with the radios installed he never got/bothered to get any other G430 paperwork/software from the previous owner..
Advices?
