11Getting StartedUsing the NAV/MOB KeyGoing to a DestinationGPS is all about marking positions as waypoints and navigating to them using the receiver’s steeringguidance and map displays. You’ve already seen how to use the ENTER/MARK key to store ourpresent position, so it’s time to move on to the fun part—going to a destination.The NAV/MOB key, located on the left side of the keypad below the PAGE key, is the primarytool used to select a destination waypoint, a route to navigate, or start a TracBack. The NAV/MOBkey can be used in three primary ways:• Pressing NAV/MOB once displays a list of options from which you can select ‘Go To Waypoint’,‘Follow Route’, ‘Follow Track’, or ‘Stop Navigation’.• Holding down NAV/MOB, or pressing the key two times, activates the MOB (Man OverBoard)feature. This marks the point at which the MOB was activated as a waypoint named “MOB” and alsoestablishes it as an active “Go To” point.• Highlighting an on-screen waypoint, map feature or map location as a destination directly from theMap Page and pressing NAV/MOB allows you to graphically select points to “Go To”.For the simulated trip, you’re going to select a pre-programmed tour route using the first method.This will also show how the MENU key is used throughout the GPS 152 system to provide tab styleoptions and functions.
