I have had NMEA 2000 networking since 1996 and moved the unit from my last powerboat to the Cal 29
So now i have a 43 year old A4 with fuel flow

and the unit has always worked perfectly
That being said it is a house of cards in that and damage to any cable kills the whole thing (the cables and wires are tiny) and my cables have become pretty stiff which is becoming and issue with the head unit on the RAM mount
Like everything else NOBODY really followed the standard ,for example the Garmin wind transducer will plug into my network BUT i will never be able to use it correctly as you pretty much need a Garmin head unit
Being and early user i am stuck with BLUE connections which have become rare as there now RED and you need adapters and then there are all the other brands of pugs that ONLY work with X
And the GPS on my hand-held Standard Horizon has incredible sensitivity (single in the basement)and it is freaking fast
