To be honest I expected way more from this upgrade…
MIssing features:
CCR mode
Change gradients while diving
Set gas as travel gasAlso…
Someone managed to activateOption to see a tissue bar graph during dive?
Is this refers to the switch window mode that switches to the tissues bar? or to add a fixed bar to the main display? -
-After turning on the knob orientation is always reset to buttons left. Would be nice if it stayed the way i configure it.
-Tide info not showing…does it use my current location? Can i somehow select a location and have the tide info shown then?
-In the app itself the underwater route…if i select a location on the map, the underwater route is not shown anymore, and cant find it anymore where that window is at.

I am having the same issue as Ray de Jager regarding button orientation. The Nautic always resets to button-left orientation after shutdown. I was told by Nautic customer support that this issue was known and would be fixed with this upgrade. But it has not. Does anyone have any information on if/when this issue will be fixed.
