[CA] [CA11] raymarine axiom

[gulfoslides]

OK, so I have a NMEA-2000 backbone. I bought a Garmin GPS 19x which outputs to NMEA-2000. I see the output of the 19x on the Axiom display so it is clearly on, and broadcasting. See this pic1 and pic2:

But when I go to the Axiom settings and select GPS and have the Axiom tell me what GPS elements it sees it only see's the internal Axiom GPS and not the Garmin 19x.
I did turn OFF the Axiom internal GPS as the default choice if GPS, but the Axiom still did not let me set the Garmin 19x as the default GPS.

I want to be able to tell the Axiom to use the Garmin 19x as the primary source of GPS input, but in the Axiom settings the 19x doesn't seem to get registered as choice. Why is that ?
