Turn the engine keys on, but the engines do not need to be running. Connect all devices and the 2 engine gauges.
CONNECT A GARMIN 545S TO NMEA 2000 NETWORK INSTALL
Install the network as per the instructions with the kit, including connecting the network power supply to a switch.

If you want to connect both engines plus the Garmin display you will need the kit, plus buy an extra T piece, plus one additional network cable of a suitable length to go from the Garmin display to the network. They also usually have two drop cables to run from other devices to the network. The kits have all the parts needed to create the network. It doesnt matter which one you use, they all work with all manufacturers displays and the plugs are all the same. Several manufacturers make these kits, including Garmin and Navico. If its not already there, then you need to create a network, and the simplest and least expensive way to create the network is to buy a “NMEA2000 starter kit”. If the network is already installed there will be a cluster of T pieces behind the dash with cables to both engine gauges and to the GPS puck antenna. Then, a NMEA2000 cable is run from the NMEA2000 plug on the back of each engine’s multifunction gauge to connect it to the network. To connect the GPS antenna to the engines, there needs to be a basic NMEA2000 network installed. Did they do that on your boat? The gauges will then use the GPS data to show speed and also real time fuel economy. Normally here in Australia, dealers include a GPS puck antenna as part of the package when they install these new Suzuki multifunction gauges. And, also make sure that the gauges in the video are the same as yours - we want to be sure that your dealer installed the Suzuki OEM gauges and did not somehow get the USA gauges that operate very differently. Watch the video and you will learn how they work. I have attached a link below to a video produced by Suzuki Australia that shows you how these gauges work. Compare what the system says to the actual amount taken to fill up. Go for a good run, use about 1/4 tank of gas, and go back immediately to the same gas pump and refill again.

fill up the tanks, and reset the gauges to full - so that fuel used figure = 0

He has never had one that gives incorrect results. I have spoken to my friend who is our local Suzuki dealer and a certified Suzuki master technician several times about this, and he confirms the Suzuki OEM gauges, once set up correctly by the dealer, are always extremely close to 100% accurate with fuel data. So, I dont know who told you that they only give you a “rough estimate” becuase that is rubbish.

They are so accurate, in fact, that there is not even an option to calibrate them like there is on the USA gauges (that are really Simrad gauges with Suzuki badges in them) The fuel flow data is sent directly from the engine’s computer and the gauges use this to calculate the amount of fuel used. The Suzuki OEM digital gauges used outside the USA since 2015 have VERY ACCURATE fuel flow and fuel used data.
