The GNC 250XL 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 250XL’s outer knob: the
active route page and the route catalog page. The active route page provides infor-
mation 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, edit-
ing, activating, deleting and copying all routes.
Routes 1-19 are used as storage routes, which are stored in the GNC 250XL’s inter-
nal 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 250XL’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 acti-
vation, 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.

C
twice and use
O

3. Use
