Acura 2011 ZDX Navigation - Manual (Page 129)

128 Navigation System
System Initialization
If the navigation system finds the
satellites properly, this box clears and
the Disclaimer screen is shown. If
within 10 minutes the system fails to
locate a sufficient number of satellites to
locate your position, the following
screen appears:
If the system is still unable to acquire a
signal, follow the instructions on the
screen, or contact your local dealer for
assistance.
NOTE:
The average acquiring time is less than
10 minutes.
Map Matching
This part of the initialization matches
the GPS coordinates found above with a
road on the map screen. To perform this
part of the procedure, ensure that the
navigation system is displaying a map,
and drive the vehicle on a mapped road
(a road shown on the map screen). Do
not enter a destination at this time.
When the name of the current road you
are driving on appears at the bottom of
the screen, the entire procedure is
complete. Your system is now ready to
use.
Although your navigation system is one
of the most highly sophisticated pieces
of equipment you will find in a modern
automobile, you may find during its use
that it has certain limitations.
The system uses GPS signals to aid in
determining its current location.
The GPS is operated by the U.S.
Department of Defense. For security
reasons, there are certain inaccuracies
built into the GPS that the navigation
system must constantly compensate for.
This can cause occasional positioning
errors of up to several hundred feet.
For example, in urban areas where
streets are close together, this could
cause the system to show that you are
traveling on a street that parallels the
street you are actually on. The system
will, under most circumstances, correct
itself while you drive.
