Hello. I have created a route for a backpacking trip in the Trinity Alps Wilderness using BaseCamp with the Topo US 24k West map. The route automatically followed the trail nicely in Basecamp. When I transfer it to the device, the route follows a straight line between waypoints, ignoring the trail. (same map on device) Any thoughts? Thanks.
