MAIN PAGES > HIGHWAY PAGE
The four data fields at the top of the page provide additional
user-selectable guidance information. Additionally, a compass
ribbon shows your current heading along with a dark vertical bar
that indicates the direct bearing to the navigation point. When the
dark, vertical indicator (or arrow) lines up with the lighter red bar
in the middle, you are heading directly to the navigation point.
Use the Highway Page as your primary navigation page in lieu of
the Pointer Page when your main concern is following a defined
course.
