Waypoints, Routes and Tracks
Waypoints are stored positions that allow you to mark areas of interest or
navigation points. Your 900 Series™ can store up to 3000 waypoints.
Routes link two or more waypoints together to create a path for navigation,
and are used in trip planning. You can link individual waypoints together by
using the GOTO key. A route represents your intended navigation and shows
the shortest path from each waypoint to the next. As you travel a route,
staying on the route line is the most efficient way to get to your destination,
although you should always look out for obstacles not shown on the chart.
Your 900 Series™ can store up to 50 routes that can each contain up to 50
waypoints.
Tracks consist of detailed position history, and are displayed as a
breadcrumb trail of trackpoints. The Current Track shows the position history
since the unit was powered up (maximum of 20,000 trackpoints displayed).
You can clear the Current Track or save it at any time. Your 900 Series™ can
store up to 50 saved tracks, each containing 20,000 trackpoints. The current
track represents your actual path so far.
