Mark,

Q1. So would you recommend the downgrade anyway?
A1. Should you the NMEA 2000 connection to the steering system be good, engines and all electronics have been switched ON, and the problem persists, then it would indeed be recommended that the software within these autopilot components be downgraded. Additionally, following the downgrade, it would be recommended that a Pilot Factory Reset be performed, that the Dockside Wizard be executed again, and that the vessel then be taken out again to determine its handling characteristics and deviation table.

Q2. Also, I'm concerned why I would be downgrading software?
A2. The EV2 - 2.17 software has been reported to have a defect which can cause the reported symptom ... hence the reason to downgrade. Again, should the problem have manifested itself after having satisfied the conditions specified above, then it would be recommended that the software within the autopilot components be downgraded to correct the reported behavior.
