Seatalk 2 fail

[LJH]

Looking for ideas as I start to troubleshoot a problem I had the other night. My autopilot went offline ("NO PILOT") followed by a "seatalk 2 fail". The bit that puzzles me is that on my RL70+ I still appeared to have all of my data that would be transmitted over seatalk (speed, depth, GPS info, etc). Anyone have any ideas?

Cheers

Check all the connections first. Unplug and re-plug everything. Worked for me.
