When included in the course file, Dash can notify you of turn by turn directions to aid in following your course. Course files may also include POI (points of interest) notifications, which can be programmed in to assist finding things along the course, such as scenic lookouts, rest stops, or stores.
A cue sheet page can also be added that shows a list of upcoming turns on the course.
To add a cue sheet page to your Dash, go to: Main menu > Settings: Profile Name > Edit data pages > Add preset page > Navigation cues.
