No Pilot error message on P70

[daknecht]

I finished installing a new e95 chart plotter in my boat today. I had an existing Seatalk ng network and EV-100 wheel pilot and those were unchanged in the install other than plugging the e95 into the network.
1. When I booted the unit up, the first message I got was to do updates. I am presuming it did that automatically from the updates I had on a chip in slot 2? It did most of the updates but failed on the update of the EV-1 (I don't remember what the message was).
2. When done, the P70 showed No Pilot. I checked power and the ACU-100 is getting power and the Seatalkng network seems to be working.
Why would the autopilot not be found?
