Thank you. I will look into that for tablets.
I started by trying the KML route. The trouble I ran into was a total inability to retain and label the points from attributes in various GIS formats after converting to KMLs and trying to configure them in the Garmin map and loading application.
I really wish Field Maps could side load like Survey123, if I could get something that can use a Mobile Map package, life would be easy, as long as we can find hardware that works in the cab of our equipment.
