How can I change the mode of the GPSMAP 196 between land, aviation, and marine?
A. After turning the GPS unit on, press the Menu button twice. Use the rocker pad to highlight the Setup tab. Then use the rocker pad to scroll to the right to highlight the System tab. Next, scroll down until the field beneath “System Mode” is highlighted. Press Enter once. Highlight the mode you wish to use, and press Enter. You may exit the menus by pressing the Quit button. For a faster method, you can also hold down the Page button for two seconds, and then use the rocker pad to select the correct mode. Pressing Enter once you have the mode higlighted will change the unit to present data for that particular mode of operation.
