Once the course select function is activated, the selected course will be displayed
next to the destination waypoint identifier and the CDI will provide guidance relative
to the desired course. The course select feature is only available during route,
approach or direct-to navigation. For more information on the course select feature

To set a desired inbound course:
1. Dial the desired course on the HSI.
