I have noticed that in my Garmin GPSmap 76CSx the boundaries of certain polygons get changed after I upload them into the GPS. It happens on shapefiles that I cut up into multiple blocks.For example a square polygon that is cut up using the cut polygon tool in ArcMap. Some of the boundries get deleted and/or some new ones are created when I view the shapefile in the GPS.
