Orientation of the Map Limitations of the Navigation System
39 You can change the orientation of the
map from North±up to Heading±up by
touching the direction symbol at the top
left of the screen.
North±up symbol
Regardless of the direction of vehicle travel,
North is always up.
Heading±up symbol
The direction of the vehicle travel is always
up. A red arrow indicates North.This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an 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 using 3 to 4 satellites. The
GPS system has a certain level of inaccura-
cy built in for security reasons. While the
navigation system will compensate for this
most of the time, occasional positioning er-
rors up to 300 feet can and should be ex-
pected. Generally, position errors will be cor-
rected within a few seconds.
When your vehicle is receiving signals from
the satellites, the ºGPSº 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 installation of window tinting may also
obstruct the GPS signals. Most window tint-
ing contains some metallic content that will
interfere with the GPS signal reception.
Lexus recommends that window tinting
should not be used on vehicles equipped
with navigation systems.
