Can you explain further what you mean about not geo-referenced.
Personally, I've never found a real use for the A+B line function of most GPS guidance systems. Everything we do is A+heading. I'm always surprised when the units default to A+B when defining new swathes. I guess maybe it's because our fields are all circles (or squares surveyed on a grid) and we tend to work them straight north and south (or on a well-defined angle like 345 or 15) to make it easy to get around the pivot. We always start to one side of the center line of the field for every operation.
