Turn by turn directions

Using the Chevreolet GPS in a 2024 Silverado 2500HD.

Yes, exploroz traveler.

Ngardanginy , probably need to give full details of how you have gone about it . Should have been pretty straightforward I would have thought ?
P.S start & finish points

Ngardanginy, try changing your mode of travel to cycle.

Changed to cycling and now have the details of the road.
?? thanks mate.

Rocco, probably is wanting Auto routing for the journey ? On the Traveller app.

Michelle, That won't explain why the straight line navigation ??

When I tried it, it took me the long way around via the Nullarbor.

I was a bit surprised that I had to change to cycle mode to get it to navigate the Great Central Road..
