I read @goldenstate's thread on installing his N200 network and, well, yikes. I just want to install a simple network so I can use the dash panel function on my Garmin. The tach is out on my '84 28+ and I'd rather have something I can read from the helm, anyway, rather than having to bend over to look at the gauges. If I could just get RPM, fuel level, engine temp senders to feed my Garmin I'd be happy. Is this a fairly simple/cheap installation? I'm not an idiot, but I'm not a rocket scientist either. Has anybody had experience with this more basic network installation?
