I have been testing with the delivered geographic coordinate systems (and setting the Auxiliary Coordinates) and I am not able to get a difference in the InRoads Tracking readout versus the ACS Position readout in the Running Coordinates.
Can you upload your DGN so we can test and try to duplicate the issue with the Lat/Long readout using the information and the geographic coordinate system stored to that DGN?
To upload the file, you can use the 'Advanced Reply Editor' and upload a single file from your computer.
