Here is my two pennyworth (as at November 23):
I beleive that the Sperry functions have been corrected except for the ‘Heading Hold’ button. (Button number 5 in the lastest edition of the manual - and not as shown above).
I think that the heading hold button has been configured as a rotary control whereas it should be a push button (so as to activate the heading hold).
That should be easy enought to fix!
