Sharing GPS from legacy unit to Helix?

[Amistad Tackle]

I have a new gen 4 MSI Helix. Got it mounted today on the console next to my eleven year old 1198. Fired it up, and the 1198 which is hooked to a heading sensor GPS puck on the stern. The two units are both connected to an ethernet box which was also powered on. The only GPS I saw in the Helix network tab to select was the internal one. I thought I would be able to share the heading sensor puck with the new Helix.

Is this not possible?

Solved my problem. One of my Ethernet boxes was not getting power. Easy fix and now I have all the GPS pucks available.
