My 787 is running 3.710 - looked last night and that is the newest update shown
as available for mine. Can't speak for everyone, but I don't even (yet) own one of
those battery adapter cables, I'm having problems with it hooked to my big
battery, in the boat. Where it rears it's head with me is when I'm trying to
study contour lines and such, looking at charts in the garage.
It won't let you do this without either being in sim, or pulling outside where
it can get satellite reception. If it can't handle just sitting there running in sim, there IS a problem. I did notice when it is one of it's particularly pi**y
moods, it seems to lock up at the same place in the "loop" of sonar that
plays during simulation. But it will sometimes do it on full chart, and at
different times. Is there not a soft and/or hard reset combo of buttons
on these???
