The Point information in the main grids can be edited. However during normal use, they are locked to prevent accidental changes. In order to Edit the points, you must click the "Edit" button. This will enable the main grids to be edited, and it will remain this way until the button is clicked again.

 

When editing, most of the information can be changed. If the coordinates are changed, the corresponding coordinate calculations are made and shown (as GPS Points/as CAD Points). If you upload to the GPS, the changed points will be used. However it depends on the GPS unit as to how it will handle points that it thinks are duplicates - some will overwrite, some will add as new. Be careful when uploading possibly duplicate points!
