Thanks, I appreciate the quick reply.
I've successfully upgraded to v2.11 now, and restoring my previously-saved User Setup does seem to have returned everything to my preferences.
I have been an IT guy, so I hoped I was able to translate the "How to Update NN3d to v2.11 (Combo Update)" instructions into a useful coarse of action. (No specific mention of Importing User Setup or Tracks after updating, several "leap of faith" (missing) instructions, first steps as paras 2.1 and 2.2 in the Appendix instead of in the main body, etc.) I guess that worked, but I believe the process could have been more clearly laid out, and in correct order instead of back to front.
I had taken extensive notes on the various menu settings... but I'd forgotten about all the talk/listen port settings in the Installation Wizard... so I had a bit of a clinch as I went through that part. I simply selected "Next" through that whole part of the Wizard, hoping for the best.
After Importing the User Setup and another reboot, it looks like the MFD-12 is good and all the other units on the network seem to be talking to each other. Importing Points and Routes worked as expected (and as in previous updates).
BUT... when the MFD starts up, I get an alarm warning: "Position Data Missing! Press Menu Button"
The first part of that shows up in Alarms/Log (tab) in the Active window briefly, and also shows up in the Log window.
Shortly thereafter, about 8 seconds, the situation seems to resolve itself, the MFD acquires position data (specifically COG and SOG, even though we're in the slip) and also sends it to the radar, VHF, etc.
Is there something about v2.11 that causes position resolution to be slightly slower than with previous versions?
