Using Fuel-Flow Information With a Garmin Chartplotter
or Marine Instrument
CautIon: The Garmin chartplotter or marine instrument must be powered on to calculate
remaining fuel based on the fuel-flow rate.
Important: When using the GFS 10 to calculate remaining fuel based on the fuel-flow
rate, you must specify the amount of fuel each time you add fuel to the tank.
To specify the amount of fuel added:
1. WhileviewingthefuelpageorfuelinstrumentscreenonyourNMEA2000orCANet
device,select
