I think its reasonable to think that some of the G1000's wiring or the
unit itself was damaged during this hack.

That would not generally cause software reboots.

It's much more realistic to think that there are fundamental defects
in the G1000.

Even attaching the power to the
ADF or entertainment system in a way that caused the power to the G1000 to
be flaky or intermittent could account for the drastic failure modes he
experienced.

There should be no drastic failure modes at all, under any conditions.
