Upgraded my e127 to the latest software release (May 2016) and now my autopilot is rendered just about useless - will not hold any course and zig zags widely when trying to use. Operating the ST60 from the MFD and prior to the update of the software it worked fine. I see a note with the software update that my autopilot will need to be recalibrated. Is this correct and if so will recalibration be required for all future software updates? Any other suggestions would be welcome if this is not a autopilot recalibration issue.
Thanks!
Thanks!
