Can I change the coordinate system of data in ArcPad?
No, you cannot change the coordinate system of data in ArcPad. Data displayed in ArcPad is not projected on-the-fly as it is in ArcMap. For ArcPad to display the layers correctly, they need to be in the same coordinate system or projection before they are brought in to ArcPad. This can be done in ArcMap, using the Projection tool in ArcToolbox.
Although ArcPad does not support on-the-fly projection for existing layers, ArcPad supports on-the-fly projection and datum conversion from the (geographic) GPS input map datum to the projection of the current map.
