The unit is set in deg/min. How do I get it to decimal notation so I can enter waypoints in decimal form. I would just as soon not have to calculate conversions for a long list.
Change the Position Format
in the Setup menu to match.
You can leave it that way or change it back to degrees.decimal minutes after.
