The GNC 250 lets you create up to 20 routes (numbered 0 through 19), with up
to 31 waypoints each. Routes are created, copied and edited through the
R
key,
which features two route pages selectable from the GNC 250’s outer knob: the
active
route page
and the
route catalog page
. The active route page provides information
and editing functions for Route 0, which always serves as the route you are currently
navigating. The route catalog page serves as the main page for creating, editing, acti-
vating, deleting and copying all routes.
Routes 1-19 are used as storage routes, which are stored in the GNC 250’s internal
memory. Once a storage route is ‘activated’, it is placed into Route 0 for navigation
until it is cancelled, overwritten by activating another route or erased when the GPS is
turned off. If you want to save a route currently in Route 0, be sure to copy it to an
open storage route (routes 1-19) before it is cancelled, overwritten or erased.
The GNC 250’s
route catalog page
is used to create, edit, delete or copy routes,
and serves as the main page for a host of functions. These include route activation,
determining the closest point of approach and search and rescue operations. It also
displays a summary of routes currently stored in memory, with the departure and
arrival route waypoints and total distance for the selected route number. To scroll
through the available routes, rotate
K
. A one-line user comment may be added to
any storage route, which will be displayed on the route catalog page.
To add user comments to any route (except route 0):
1. Rotate
K
to display the route you would like to add comments to.
2. Press
C
twice and use
O
to highlight the bottom row.
3. Use
K
and
O
to enter comments, and press
E
. To erase, press
\
, then
E
.
