B&G or NKE to Nexus

[bojo_bs]

Hi! My friends from the club plan to participate single or double handed Atlantic Ocean race Ostar/Twostar next year. The boat is equiped with Nexus NX2 race system. They have broken autopilot, which I repair and I"m proud with that. But as I see this autopilot haven't TWA and when the boat is in downwind not perforn well. Suddenly makes jybes and course changes over 40 degrees on waves. I see in other threads that Nexus autopilot not performing well in downwind.

So please recommend me an autopilot, which supports TWA to connect to existing Nexus network. They also have GND10 Black box/NMEA2000 converter. I ask NKE for support two weeks ago, but no answer. I didn"t ask B&G.
