Viewing Your Path on the Highway Page
When a route is initiated, the Highway Page provides digital and
graphic steering guidance to the destination. A compass ribbon
appears at the top of the page to show your current heading,
represented by the violet bar. The red vertical bar represents the
bearing to your course. To stay on course, steer towards the red
vertical indicator (or arrows) until it lines up with the violet bar
in the middle. The bottom section of the screen provides visual
guidance to the waypoint on a graphic highway display. The line
down the center of the highway represents your desired track line.
