I am preparing to install the factory option Garmin 742xs in my 2016 226. I have ordered the unit, transducer, and woodgrain bezel. The dealer is not showing any additional parts required to the install.
It seems like there would be a harness to go from the digital gauges to the unit. Does anyone know if there is an existing Nmea 2000 network from the factory or what is required to tie the engine data to the GPS unit?
