ROUTE NAVIGATION
In many cases a trip from one place to another involves several course
changes, requiring a series of route points (waypoints) which you
navigate to, one after another. The sequence of waypoints leading to
the ultimate destination is called a route. This unit can automatically
advance to the next waypoint on a route, so you do not have to change
the destination waypoint repeatedly. The figure below shows an ex-
ample of a route between two points, involving six waypoints.

Figure 5-1 Sample route
You can store 10 routes and a route may contain up to 15 waypoints.
The 3300 automatically assigns a route number from 0-9. Be sure to
record all important routes in a separate log and save them to a memory
card. This unit is not a fail-safe record keeping device.
