I only ever use a Garmin for nav backup but am writing about phones.
I know they can show your location with GPS when there is no signal – of use with pre-downloaded maps.
But will an imported tracklog (called 'GPX route file' on walking highlands - continuous line) also show up in a mapping app without mobile signal?
Searched but could not find.
Thanks
