NMEA 2000 Updating software

Adam Body

I have just installed a new chartplotter with prexisting NMEA 2000/ Seatalkng components and spent significant time sorting out a problem with as it turned out a simple solution.  The solution to components not communicating correctly was to disconnect all but the one requiring the update, update that one, then continue in the same way with the other components. Hope this helps others in the group.
