I did ajust the CAL factor up and down to no avail.
The SOG can only be adjusted when you have other raymarine instruments connected with the seatalk cables.
I do not have a raytheon chartplotter or gps or anything else ...
so I think I am only possible to adjust the CAL factor
Correct me if I am wrong though
