All GPS units work in the native "Satelite" datum of WGS-84. The points are stored in the GPS unit's datababase using this format. When GPS2CAD recovers the points they are shown in both the Lat/Long WGS-84 datum, and the User Selected "Cartesian" grid/datum that will be used to plot the points in AutoCAD/CAD.
