I am taking delivery of my Helix 10 mega today and heading to the water this weekend to install. I have a merc monitor currently on the boat and was needing nmea 0183 output on the head unit so the mercmonitor gets the gps data.
I have been unable to find the wiring diagram or info on the newer units for this.
Can anyone help out with wiring in the merc monitor to the NMEA output on the helix?
