There is a back cover included with the mast bracket which will house the wire harness used to connect the instruments. Got some information at the boat show in Dusseldorf: However, it’s usually not that hard to fit a multi-port or several tees screwed together somewhere nearby and all the displays can be on one spur from the backbone as long as the total cable length from backbone to any one display doesn’t exceed 6 meters. Daisy chaining N2K instruments makes for a very tidy install, though failure of one can mean data loss for all others down stream. What I bet Garmin did not do is put a second N2K port (female) on these displays because it’s against the NMEA rules (though it’s a really questionable rule, I think, and just about all the instrument competitors break it). In fact, if the 0.4W max spec is correct (HV is close) you could run 6 of the 10-inch GNX displays on the max 2.5W used by Garmin’s GMI 20, which is powered by the N2K bus. Isn’t that a proprietary B&G protocol?:Īlso I don’t see anything to indicate that these Garmin displays will need separate power feeds.
Tom, I thought that too but when I looked this morning the online specs for B&G HV displays all say the interface is Fastnet. Overall, though, I guess these new Garmins are the first NMEA 2000 maxi displays (though I wouldn’t be surprised to see similar from B&G and maybe Raymarine). So far Navico has shown more willingness to work with independent marine developers but I notice that Garmin is opening up more in other areas like smart watches:

So one question for the Garmin developers is whether they plan to push their own sailing-specific values to the GNX displays.Īllowing third party software to push values through the system is another matter, but it’s certainly possible, even via WiFi. But N2K does permit proprietary PGNs and the new Garmin Start Guidance is already generating values like Time-to-Burn and Distance-to-Line that would be great to have on the big mast displays for all the crew to see (particularly the trimmers). To my knowledge there are no standard NMEA 2000 PGNs that cover the information you mention (though the online database - is out of date). Note that the “ 256″ and “78” on the depth screen above are max/min for the graph time period, which is user configurable.Įxcellent point, Jukka. The top portion of the big “hybrid” LCDs seem to use efficient segmentation while pixels on the lower portion permit graphics and the whole power load is said to be less than 0.4 Watts night or day for either size. I can picture these displays becoming popular on high-end motor yachts - much as B&G instruments have earned space on many megayacht bridges - but obviously the focus is performance sailing.

Over 50 NMEA 2000 data types will be recognized and there will be five display configurations including “single, dual and triple functions, plus Gauge and Graph mode”… Set up is done with those onscreen touch buttons or with a new GNX Keypad. They use what’s called “high-precision glass-bonded monochrome ultra-glow LCD displays” and the data backlighting can be switched to most any color. This morning Garmin announced the $900 7-inch GNX 120 and the $1,500 10-inch GNX 130 (above) with planned delivery in February and May respectively.
