We recently put a re-paneled Duo Discus into service with a Clear Nav and
CN vario (which I like a lot). We discovered the type of switch you have
(ON-OFF-ON) would re-start the ClearNav no matter how quickly it was
flipped. We have gone to a switch for each battery and the protocol is
to turn on the subsequent switch before turning off the first one. No problems.

Now keep in mind that I am a software guy and know just enough about
electronics to be dangerous, but couldn't you just wire in a sufficiently
large capacitor to bridge the temporary loss of power? I seem to remember
something like that in the wiring instructions for my Volkslogger.
