I am not sure about the 600 but I was into a 500 last week and it had the
little standoff daughter board with a rechargeable memory cell on it. These
are in numerous Raytheon and other vendors products. Take a peek at yours
and see if the cell has started to leak. If so, get it to a qualified repair
center ASAP. These leaking cells will eventually eat up circuit board
traces, etc. Many an intermittent is caused by the corrosive action of the
leaking chemical on adjacent circuitry.

Does anyone out there have a Raymarine Navcenter 600? Mine has strange
behavior. It turns itself off after 20-30 minutes of operation. I don't
see
a pattern. At first I thought there might be an "idle timeout" where it
turns itself off after a certain amount of inactivity. Today, at the dock,
I
was programming some route info into it and after about 30 minutes it
turned
itself off. It would not immediately turn back on. After a couple minutes,
it did come back on, but then turned itself off again after 20 minutes.

So, I presume this is not normal behavior, a timeout, or such. Perhaps it
is
an overheating problem?

Anyone have any ideas about this phenomenon?

Thanks,
