Default Garmin to VHF GPS position

Garmin 1040xs will not transmit GPS to VHF.

It was working then I added a NMEA 2000. Only thing hooked up through NMEA 2000 is the Honda, I wanted my engine info on the Garmin.

Prior to hooking up the Honda via NMEA 2000 I was able to see my GPS position on my vhf.

I feel it’s a setting in the Garmin but not sure where to start.

On a side not I was able to connect my Honda to my Garmin so I have all my engine data on the Garmin.

Maybe try disconnecting the engine and see if the GPS info starts transferring again?

Second thing I would check would be for a proper NMEA 2000 setup.
1 backbone cable
3 T-connectors
3 drop cables (from engine, VHF, and plotter)
2 terminators (1 male, 1 female)
1 power tap connected to +12 V
