BASIC FUNCTIONS
51
When you are driving while the route
guidance is operating, you can change
the route to detour around a section of
the route where a delay is caused by
road repairs, an accident, etc.
Select the “Chg. route” switch on the
right side of the screen if you encounter
a reason to divert from the selected
route.
This picture shows an example of how the
system would route you around a delay
caused by a traffic jam.
1 This part indicates the location where
traffic jam is occurring due to road re-
pairs or an accident.
2 These show the detour route sug-
gested by the system.
When you select the “Chg. route”switch, the screen changes to the “Change
route” screen that allows you to select the
distance you want to detour. Select one of
the numeral keys to start the detour pro-
cess. After detouring, the system returns
to the original guidance route.
“Whole route”: If you select this switch,
the system will calculate an entire new
route to the destination.
INFORMATION
 When your vehicle is on a freeway,
the detour distance selections are
5, 15 and 25 miles.
 The system may not be able to cal-
culate a detour route depending on
the selected distance and sur-
rounding road conditions.
“Search condition”: To change the con-
ditions of the searching route. (See page
101.)
“Quick”: A route on which you can reach
the destination in the shortest time.
“Short”: A route on which you can reach
the destination in the shortest distance.
“Alternative”: Other route.

BASIC FUNCTIONS

This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate posi-
tion may not be shown depending on
the satellite condition, road configura-
tion, vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position, normally using 4 or
more satellites, and in some cases 3 satel-
lites. The GPS system has a certain level
of inaccuracy built in for security reasons.
While the navigation system will compen-
sate for this most of the time, occasional
positioning 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 not receiving signals
from the satellites, the “GPS” mark does
not appear at 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 placement of
objects on the instrument panel may ob-
struct 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 good 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 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.
