On a recent trip, I set my raymarine
a78 to night mode. After a few hours, it would spontaneously go from either the chart plotter screen
or the radar screen
back to home. Eventually it did all sorts of other unwelcome behavior.
I finally figured out that the failure was repeatable in night mode and not repeatable in day mode.
I have posed the problem on the ray marine
site with no answer.
Has anyone seen this? Is this a problem with the unit in general, an impending general failure, or a software
bug that may Mor may not have been fixed.
