The C-series unit you have is NOT networkable - There is no such thing as a "secondary" display with it. You'd have to have a full set of cables
at both locations - this isn't really a problem for power and SeaTalk
- just a matter of finding the right cables
them in since you can tap these anywhere. If you have NMEA0183, it's also workable since the wiring is pretty simple. But, If you have radar
, depthsounder, or weather
modules, then it will be problem as these are point-to-point cables.
I have a C70 at my helm. I just do my planning sitting at the nav station on the computer, then transfer to the chartplotter
via NMEA0183 network or CF cards... Works for me, not sure if it will work for you, but it's an option.
