GETTING STARTED
Using the GOTO Key
GPS is all about marking positions as waypoints and navigating to them
using the receiver’s steering guidance and map displays. We’ve already seen
how to use the M key to store our present position, so it’s time to move on
to the fun part: going to a destination. The G key, located on the left side of
the keypad above the Q key, is the primary tool used to select a destination
waypoint or a route to navigate. The G key can be used in three ways:
• Pressing G once displays a list of all waypoints in memory, from which
you can select a single destination waypoint.
• Pressing G followed by the O key provides a list of GOTO options
that lets you start a TracBack route, select a destination waypoint from the
nearest waypoints list, select a stored route to navigate, or cancel the
current GOTO destination.
• Pressing G twice allows you to graphically select an on-screen
waypoint, navaid or cursor position as a destination directly from the
map display.
For our simulated trip, we’re going to select the preprogrammed tour route
(the second method), which will automatically place our vessel at the first route
waypoint. This will also give us an idea of how the O key is used throughout
the GPSMAP 175 system to provide options automatically oriented toward the
function currently in use. Let’s give it a try by activating the practice route stored
in memory for navigation:
1. Press G. The waypoint list page will appear. (If we were selecting a
single waypoint to navigate to rather than a route, we would highlight the
waypoint and press T.
2. Press O to display the context-sensitive options available for the GOTO function.
3. Use the R keypad to highlight the ‘Select Route?’ option. Press T to confirm.
4. The select route page will appear, with the ‘GPSMAP TOUR’ route highlighted.
5. Press T. The map page will reappear and display five waypoints chained
together in a simple route, with your boat at the first route waypoint.
