I just ordered a tablet PC with sunlight readable display. I'll be
spending
a very long summer cruising. Trying to get everything connected to it
wirelessly will give me something to do during those long northern
evenings.
I think I prefer BT for power drain reasons. It should do everything I
need
to do. I have Simrad IS15 instruments and a AP16 autopilot. My first
goal
will simply be to get the GPS signal through BT to the tablet. Then add
in
the rest of the IS15 instruments, then navigate from Visual Nav Suite. If
I'm really having fun I may add in the engine and electrical instruments
as
well.

Do you see any reason I would need the 42 series or would the 41 suffice?

If you receive all the data via the mux to the tablet and let the tablet
drive the autopilot (mux in server mode), a -41BT will do. If for some
reason the instrument data needs to go to the autopilot too (mux in hub
mode), you might get too much data on the 4800 baud output and you might
need to use a -42BT with it's sentence filtering capability, to get rid of
unwanted data into the pilot.
