which i have put in my gpx file on the Nav 6.
How (exactly) did you put the route into your gpx file on the Nav VI?
Also I have imported in using BaseCamp again
How (exactly) did you do this?
Are you using a PC or a Mac?
Failing any of that. If you didn’t get a pop-up on the device saying something along the lines of, ‘New data found, would you like to use it?’, try the following:
Home screen
Apps
Trip Planner
Three horizontal lines, top left corner, touch
Import
Select the route(s) you want, scrolling down if necessary
Import
A pop-up will then say it is saving the item(s) to trip planner, calculating.... This might take a while, so be patient
Return to trip planner
Find the route(s) you imported from the device’s internal memory and away you go
PS Always check that what the route the device is now showing on its navigation screen is about right, before you hoon off
