I've received the GPX Files from 4x4WA for Mundairing to Albany, 'The Track' Ok where Im at, techno phobic, got the gear but have FA idea !! Im using Basecamp and want to get the track to a route then onto my Zumo 590. When I download the GPX files into Basecamp this rubbish happens in two areas. Further up and here on this screen grab. Ive tried finding the corrupt points but no luck. Is there anywhere that teaches old idiots like me how to work this thing ?? Cant figure out how to make it right. Funnily enough though I just did it all on my Samsung S9+ opening the GPX file from my Gmail and putting it on OSMAND without one iota of issues like garmin is giving me !!!!
