APPENDIX
This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, the accurate position
may not be shown depending on the sat-
ellite condition, road configuration, ve-
hicle condition or other circumstances.
The Global Positioning System (GPS) devel-
oped and operated by the U.S. Department
of Defense provides an accurate current ve-
hicle position, normally using 4 or more satel-
lites, and in some cases 3 satellites. The
GPS system has a certain level of inaccura-
cy. While the navigation system will compen-
sate for this most of the time, occasional
positioning errors of up to 100 m (300 feet)
can and should be expected. Generally,
position errors will be corrected within a few
seconds.
When your vehicle is receiving signals from
the satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display. Tunnels, tall build-
ings, trucks, or even the placement of objects
on the instrument panel may obstruct the
GPS signals.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.
Even when the navigation system is receiv-
ing clear GPS signals, the vehicle position
may not be shown accurately or inappropri-
ate route guidance may occur in some
cases.
NOTICE
The installation of window tinting may
obstruct the GPS signals. Most win-
dow tinting contains some metallic
content that will interfere with GPS sig-
nal reception of the antenna in the in-
strument panel. We advise against the
use of window tinting on vehicles
equipped with navigation systems.
