Magellan RoadMate POI Manager

The Magellan RoadMate POI Manager enables you to transfer custom points of interest
files from your computer to your Magellan RoadMate 2200T.
Before we add any custom POI's to the Magellan RoadMate 2200T, you should
understand how the POI Manager plots POIs.

Latitude

Latitude can be expressed by dividing Earth into
horizontal segments totalling 180 degrees.
Starting at the Equator, or zero degrees Latitude,
lines (or Parallels) are drawn in 10-degree
increments 90 degrees to the north and 90
degrees to the south. If your location is below the
Equator, you are at a South Latitude.

Longitude

Conversely, longitude lines can be expressed by
dividing Earth into vertical segments totalling
360 degrees. Starting at the Prime Meridian
(which is The Royal Observatory in Greenwich,
England), or zero degrees Longitude, lines are
drawn in 10-degree increments 180 degrees to
the West and 180 degrees to the East. If your
location is on the western hemisphere, you are at
a West Longitude.
Additionally, to narrow down your location
further, each 10-degree segment is divided into 60 smaller segments called minutes and,
still further, each minute is divided into 60 segments called seconds.
To express this in coordinates, the city of Los Angeles is located at 34° (degrees) 03'
(minutes) and 08 (seconds) North of the Equator, and 118° (degrees) 14' (minutes) and
42 (seconds) West of the Prime Meridian.
