Navigation System 97
System Limitations
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 Global Positioning
System (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.
Depending on your current view of the
sky and the position of the satellites, the
elevation may be shown incorrectly.
You may also notice some delay of the
vehicle position icon at intersections;
this is normal.
GPS Reception Issues
The signals received from the GPS
satellites are extremely weak (less than
a millionth of the strength of a local FM
station) and require an unobstructed
view of the sky. The signal can easily be
interrupted or interfered with by the
following:
• Aftermarket metallic window tint
above or to the sides of the GPS
antenna (located under the
dashboard)
• Cell phones, PDAs, or other
electronic devices docked in a cradle
or lying loose on the dashboard
• Radar detectors mounted on the
dashboard
• Remote starters, or “hidden” vehicle
tracking systems mounted near the
navigation unit
• Other aftermarket audio electronic
devices mounted near the navigation
unit
• Trees, tall buildings, freeway
overpasses, tunnels, or overhead
electrical power wires
Although the system will direct you to
your desired destination, it may not
always generate what you consider to be
the most direct route. Try changing the
method of routing. See Changing the
Routing Method on page
45 . You may
also have Unverified Area Routing set
to OFF. See Unverified Area Routing on
page
82 .
Additionally, the mapping database
contains verified and unverified maps.
See Map Overview on page
6 . A
Disclaimer screen will warn you if your
route includes unverified streets.
Unverified streets may be missing from
the map, in the wrong location, or have
an incorrect name or address range.
Exercise additional caution when
driving in these unverified areas.
