As Courses have been added in firmware 10.50, settings for 'Calculation Method', 'Off Route Recaulation' and 'Avoidance Setup' have been moved into a sub menu.
I wonder, if this is indented, when 'Course Navigation Method' is set to 'Direct Path', you can still configure those three mentioned settings. This could lead to a false asumption, as in direct mode, those options should have no impact in 'Direct Path'? So maybe the should be greyed out or something like that?
