from many different manufacturers - each piece chosen based on our needs and preferences and not on fear it wouldn't work with other components. Even our autopilot
consists of mixed manufacturers. Everything works perfectly together.
My suggestion is to shop for each part individually and make your decision on what features, cost, size, performance etc you like. Make sure they are all fully N2K compatible (I think a few pieces of Raymarine gear is the only hold out on this), and hook them together. Your radar
and chart plotter will most likely be the same manufacturer because they will use the same display. Radar
is the only thing that is not mix and match.
We were struck by lightning
with our old NMEA0183 instruments (including wind), and it took out everything. I don't see why N2K would be considered more vulnerable.
At the present state of play , I won't say mixing NMEA
2k gear is the greatest advice. There are lots of example where MFD integration and particularly device configuration don't work across brands. Your advice is " ok " for sensors and transducers , but not for higher order equipment
to mfd integration. Etc. for example the very fine Simrad
mfd based autopilot control software
will not integrate properly with non simrad autopilots.
This is because there are large areas of nmea2k that are not standardised
