I started using GPS for navigation on sailing boats over 20 years ago,before that Decca,and Loran was still being used.
I always plotted postions on chart every hour or less inshore or in busy shipping lanes,and cross checked both ways chart-GPS.
The last boat had a chart plotter in 1990,ie glass cockpit
linked to radar and autopilot.
Why has it taken so long for GA to catch up?
The advice to not rely soley on an electronic device is,I believe,sensible.
Use the GPS but update the chart as you go.
