Edit a waypoint’s position 
by entering the new position 
coordinates directly over the 
old position.
From the Waypoint Edit Page, highlight the appropriate field to rename a 
waypoint, change its symbol, edit the comment or edit the position.
To rename the waypoint:
           1. Highlight the waypoint name field and press ENTER.

‘Display Options’ lets you 
determine what waypoint 
information will appear on 
the map display.
The  Waypoint  Edit  Page  also  features  an  options  page  that  allows  you  to  delete 
the  waypoint,  view  the  map  area  around  the  waypoint  position,  define  how  the 
waypoint  will  appear  on  the  map  display  or  average  the  waypoint  position  to 
improve accuracy.
To display the Waypoint Edit Options, press MENU (with the Waypoint 
Edit Page displayed).
The following options are...

The nearest locations pages are 
organized as a series of “file 
tabs”. Select the appropriate 
tab to show as many as nine 
nearby waypoints, 50 nearest 
cities or 50 nearest highway 
exits—along with the bearing 
and distance to each.
Another  waypoint  feature  of  the  GPS  III+  is  the  nearest  locations  pages,  which 
show  up  to  nine  nearest  waypoints  and  50  nearest  cities—within  200  miles  of  your 
present  position—along  with  50  exits  on  the  nearest  (interstate)  highway...

    To GOTO a nearby location:
           1.  Highlight the desired location on the selected nearest list. Press GOTO to display the 
GOTO Page with the desired location selected.
           2.  Press ENTER to confirm the selected waypoint and begin navigating.
Nearest Location Options
The  nearest  locations  pages  also  feature  an  options  page  that  allows  you  to 
define the category of items you want to appear on the Nearest Cities, Exits or Geo 
Pnts Lists or restore the factory default...

The GPS III+ can navigate to a destination using any of four different methods:
  GOTO— lets you select a waypoint as your destination and quickly plot a direct 
course from present position to that waypoint. 
  MOB  (man  overboard)—  captures  your  present  position,  saves  it  as  a  waypoint 
and sets a course back to the position for quick response in an emergency.
  TracBack—  allows  you  to  retrace  your  path  using  the  track  log  automatically 
stored in the receiver’s memory. This...

To designate a GOTO waypoint from a list of waypoints:
           1. Highlight the desired waypoint on the list and press GOTO. A confirmation page shows
                the selected destination waypoint.
           2. Press ENTER to confirm the selected waypoint and begin navigating.
To GOTO an existing waypoint, city or highway exit on the map display:
           1.  Use the rocker keypad to place the arrow on the desired target location. If a city or exit 
is selected, a waypoint will be created at...

Cancel  GOTO—  cancels  the  current  GOTO  destination  and  resumes  navigation 
       of any previously selected route. If no route is currently in use; bearing, distance, 
       etc. will remain blank until a destination waypoint is defined.
To cancel the current GOTO destination, highlight ‘Cancel GOTO’ and 
press ENTER.
MOB (man overboard)
The  GPS  III+’s  MOB  function  lets  you  simultaneously  mark  and  set  a  course  to 
a  position  for  quick  response  in  an  emergency.  Once  an  MOB...

The  TracBack  navigation  feature  allows  you  to  retrace  your  path  using  the  track 
log automatically stored in the receiver’s memory. This eliminates the need to manually 
store  waypoints  along  the  way.  A  track  log  is  an  electronic  breadcrumb  trail,  showing 
the path you have travelled. Your GPS III+ can be set to automatically record track log 
points any time the receiver is on and locked onto satellites (see page 71). 
TracBack  routes  are  created  by  reducing  your  track...

Once  a  TracBack  has  been  activated,  the  GPS  III+  will  take  the  track  log  currently 
stored  in  memory  and  divide  it  into  route  segments,  called  ‘legs’.  Up  to  30  track  log 
waypoints  (labeled  ‘T###’,  e.g.  ‘T001’)  will  be  created  to  mark  the  most  significant 
features  of  the  track  log  in  order  to  duplicate  your  path  as  closely  as  possible.  To  gain 
the most benefit from the TracBack feature, keep the following tips in mind:
•  Always  clear  the...

Route  navigation  allows  you  to  manually  create  a  sequence  of  intermediate 
waypoints which lead you to your final destination. The GPS III+ will store up to 20 
reversible  routes,  with  up  to  30  waypoints  in  each  route.  Routes  can  be  created  and 
modified by text entry (using the rocker keypad to enter waypoint names) or directly 
from the map display. Using the map display allows you to see each route graphically 
on-screen  as  you  create,  review,  modify  or  navigate  the...
