NAVIGATION SYSTEM
5. GPS (GLOBAL POSITIONING SYSTEM)
1. LIMITATIONS OF THE NAVIGATION SYSTEM
The Global Positioning System (GPS)
developed and operated by the U.S. De-
partment of Defense provides an accu-
rate current position, normally using 4
or more satellites, and in some case 3
satellites. The GPS system has a certain
level of inaccuracy. While the naviga-
tion system will compensate 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 the vehicle is receiving signals
from satellites, the “GPS” mark appears
at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map screen. Tunnels, tall
buildings, 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 re-
ceiving clear GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur
in some cases.
This navigation system calculates
the current position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate posi-
tion may not be shown depending on
satellite conditions, road configura-
tion, vehicle condition or other cir-
cumstances.
NOTICE
The installation of window tinting
may obstruct the GPS signals. Most
window tinting contains some metal-
lic content that will interfere with
GPS signal reception of the antenna
in the instrument panel. We advise
against the use of window tinting on
vehicles equipped with navigation
systems.
