[CA] Axiom Pro Heading Data from Autopilot

[Kevin]

Just completed installation of 2 new Axiom Pro MFDs, with i60/i50 + i70s instruments, iTC-5 for all the transducers.

There is currently a Simrad J300x-40 autopilot installed in the boat.

For whatever reason I can NOT get heading data on the Axiom Pros.

Tried using the 0183 Tx/Rx ports straight to the 16" Axiom Pro which didn't work so I used an Actisense NGW-1 we had on hand. Directly connected the NGW-1 to the Tx/Rx port 2 on the J300x then adapted the DeviceNet cable to my STng network.

On the Axiom Pro I can go to Settings> Network> Data Sources I can select the iTC-5 for the depth, wind etc but for Heading it won't detect any source.

However, on the i70s instrument I can go to Menu> Set-Up> System Set-Up> Data Sources> Heading I can choose between "Auto" and "NMEA2000<_>018"
This allows me to get Heading on the i70s so I know it's available on the STng backbone.

Any thoughts?
