Labeling of shapefiles converted in GPX files

[Brett Sutherland]

Good Day

I have got a large number polygons defining centre irrigation pivots within a estate, each of these pivots have identification numbers. When I convert these polygons into the format required using Mapwel and upload the map into the Garmin GPS these labels, although displaying in Mapwel, don't show in the Garmin GPS. Please could someone assist me.

Regards
Brett
