When I tried to edit the page there was no coolant pressure to select. Should I assume if there is no PGN present there will be no coolant pressure to select?
Today i checked pgn inputs on my Garmin plotter and it did show it was receiving
PGN 127489. Since it and my TZTXL are on the same N2K buss i would think it is receiving that PGN. Do i need to turn something on in the TZTXL?
