Getting StartedUsing the NAV KeyGoing to a DestinationGPS is all about marking positions as waypoints and navigating to them using the receiver’ssteering guidance and map displays. We’ve already seen how to use the ENTER/MARK key to store yourpresent position, so it’s time to move on to the fun part—going to a destination.The NAV/MOB key, located on the keypad above the QUIT key, is the primary tool used to select adestination waypoint, TracBack, or a route to navigate. The NAV key can be used in two primary ways:• Pressing NAV once displays a list of options from which you can select ‘Go To Point’, ‘FollowRoute’, ‘Follow Track’, or ‘Stop Navigation’.• Highlighting an on-screen waypoint or map item as a destination directly from the Map Page andpressing NAV allows you to graphically select points to “Go To”.For our simulated trip, you’re going to select a pre-programmed tour route using the first method.This also shows how the MENU key is used throughout the GPSMAP 178/178C Sounder system toprovide tab style options and functions.
