[CA] [CA11] Evolution autopilot speed input question

[Mauro]

Hello. I just installed a new ev100 autopilot on my 30 feet sailboat. Everything is working ok, I was able to calibrate the autopilot and tested a little bit and looks fine. However, I have a doubt regarding speed input. As in my case the SOG is much more accurate than the STW, I’d like to select SOG as the default speed input. I read this threads to learn how to do it:

However, I can't find the GPS SOG option in MENU->SET-UP->AUTOPILOT SET-UP->VESSEL-SETTINGS->SPEED INPUT. The only option displayed other than the AUTO is the
ITC-5 one. The SOG is displayed in the data box of the control head and looks accurate, so I assume the information is available, but I wonder how to choose the SOG as the default speed input. Any suggestion?

My sailboat equipment and software versions:
a68 v19.03
i70 v3.07
P70s v3.07
St-stng conv v2.03
Acu100 v2.17
Ev1 v2.17
Itc5 (for stw, wind and depth) v1.12

Thanks in advance and Happy new year!
