The Global Positioning System (GPS)

This feature uses information from the Global Positioning
System (GPS) satellites orbiting the Earth to determine the
approximate geographical location of your radio, expressed as
latitude and longitude. The availability and accuracy of this
location information (and the amount of time that it takes to
calculate it) varies depending on the environment in which you
are using the GPS feature.
For example, GPS location fixes are very difficult to obtain
indoors, in covered locations, between high buildings, or in
situations where you have not established a clear broad view of
the sky.

Understanding the GPS Feature

The GPS technology uses radio signals from earth orbiting
satellites, to establish the location coordinates, maximizing your
view of clear unobstructed sky is essential for optimum
performance.
Where adequate signals from multiple satellites are not
available (usually because you cannot establish a view of a
wide area of the sky), the GPS feature of your radio will not
work. Such situations include but are not limited to:
In underground locations
•
Inside of buildings, trains, or other covered vehicles
•
