This navigation system calculates the 
current vehicle position using satellite 
signals, various vehicle signals, map 
data, etc.    However, the accurate po-
sition may not be shown depending 
on the satellite condition, road con-
figuration, vehicle condition or other 
circumstances. 
The Global Positioning System (GPS) 
developed and operated by the U.S. 
Department of Defense provides an ac-
curate current vehicle position, normally 
using 4 or more satellites, and in some 
cases 3 satellites.  The GPS system 
has a certain level of inaccuracy.    While 
the navigation system will compensate 
for this most of the time, occasional posi-
tioning errors of up to 300 feet (100 m) 
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 ap-
pears at the top left of the screen. 
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle 
position on the map display.  Tunnels, 
tall buildings, trucks, or even the place-
ment 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 re-
ceiving clear GPS signals, the vehicle 
position may not be shown accurately or 
inappropriate route guidance may occur 
in some cases. 
 
NOTICE 
The installation of window tinting 
may obstruct the GPS signals. 
Most window tinting contains some 
metallic content that will interfere 
with GPS signal reception.    We ad-
vise against the use of window tint-
ing on vehicles equipped with navi-
gation systems.
