Entering Speed and Fuel Flow for Trip Planning

of the units of measure (gallons or liters).

From the Route tab option menu, highlight Set Up Routes and
press ENTER to set the route leg transition (or waypoint transition).
Select Distance to enter a radius so that when you are within the
entered distance, the GPSMAP 278 leads you to the next point on
your route.
When you select Manual, you can transition to the next waypoint
anytime while navigating a route. While you are navigating the
route, open the Active Route Page. Press MENU. Highlight Next
Route Waypoint and press ENTER to have the GPSMAP 278 start
routing you to the next point in your route.
