[C320-list] Autohelm Upgrade

[Steve Weinstein]

 Chip, all the equipment that I had on the C270 was Raymarine, so it all networked together with SeaTalkng.  I did have to use an ITC-5 to connect the speedo and depth to the network.  But it all worked great.  The EV-100 was an easy setup.  Later, I added a B&G wireless masthead wind speed/direction unit, which is a NMEA 2000 unit.  It connected directly into the STng network through the receiving unit that I installed in the Navpod, with a simple NMEA 2K to STng cable.  Again, the setup was simple and everything worked together nicely.
I have an EV-100 sitting in the garage that I intend to install in place of the old Raytheon unit that I believe was original equipment on the boat (Vega).  All the stuff on the boat is Raymarine/Raytheon and is working fine with my Axiom 9RV MFD.  I'm hoping the EV-100 will integrate easily with the existing setup.

 Thanks so much, Steve.

For laughs, here are the one lines for my electronics system (attached), a
mix of old and new Raymarine and a Garmin GPS 421 chartplotter.  I don't
yet have the NGT-1 and iPad in the system, but I plan to add them if I need
to debug any of the messages after final setup.  Did you have any issues
with your autohelm system getting everything to play nice during initial
testing?

Best,
