Main Pages

The Map Page is one of six main pages used in the GPSMAP 188/188C/238 Sounder’s system. The

six main pages are the Map Page, Sonar Page, Compass Page, Numbers Page, Highway Page, and Active

Route Page. All six pages are linked together in a simple chain, which allows you to scroll through the

pages in either direction using the PAGE and QUIT keys.

Map Page

The GPSMAP 188/188C/238 Sounder’s Map Page combines digital chartplotting with a user-select-

able display of navigation data and a built-in worldwide database. It will also be the page you use most

to create and edit waypoints and routes. Before we take off on our practice route, let’s take a brief look

at its various features and displays.

The map display shows your “boat” as a triangle marker on an electronically generated chart.

Geographic names, roads, markers and buoys that are provided by the optional BlueChart or

MapSource data are also shown. It also displays your track, routes and nearby waypoints. An on-screen

cursor lets you pan to other map areas, determine the range and bearing to a position, and perform

various waypoint and route functions.

The data window, located at the top of the page, provides a user-selectable display of various navi-

gation data, including speed over ground, distance to the next navigation point, compass ribbon, and

current position coordinates. The current map scale setting is located at the bottom right of the page.
