I know that this won't help you, but for others reading, NMEA 2000
solves many of these problems. I just installed a NMEA 2000
network on our boat. Easy as making some connections, running some wires. The GPS talks to the chartplotter
, autiopilot to chartplotter
is available on chartplotter and Gamin GMI-10 diplay, etc. The long awaited radio
I am receiveing in a week or two , a Lowrance LVR-880, will hookup to the network and use the network's GPS. I can even show up to three "Buddy" boats on the chartplotter, if they are using their MMSI (or whatever that is called) radio
with GPS attached, and I have their number. Cool, eh?
I was starting from almost scratch, so it was an easy decision.
