So Im not sure if it is supposed to or not but the boat had a $919 option for the Simrad installed and all that shows up on the control screen is the GPS speed water temp and depth. None of the other dials read, the RPM, fuel, trim and I don't know if they should or not. Being a factory option I would think it would?? The boat has analog gauges for the trim/rpm/fual and they all work as they should. Does anyone have experience with this?
