Glossary
•Wide area map, detailed map
The wide area map is a map of a la rge area, and the detailed map is a 
map of a small area. The scales  of the maps are 1/20,480,000, 
1/10,240,000, 1/5,120,000, 1/ 2, 560,000, 1/1,280,000, 1/640,000, 
1/320,000, 1/160,000, 1/80,000,  1/40,000, 1/20,000, 1/10,000, and 
1/5,000.
• Positioning
The quality of the GPS positioning is  displayed in the top right of the 
menu screen. The greater the number of displayed symbols, the 
higher the precision of the GPS positioning. •
2D positioning and 3D positioning
GPS calculates positions using triangulation.
The distance to the satellite can be determined when the radio wave 
from that satellite is received,  and the current location can be 
measured by receiving radio waves from 3 satellites.
However, because there is a margin  of error in the GPS satellites and 
navigation unit, positioning is performed in only the 2 dimensions of 
latitude and longitude when radio  waves from only 3 satellites can 
be received. The precision will be  lower in this case. When radio 
waves from 4 or more GPS satellites are received, positioning is 
performed in the 3 dimensions of la titude, longitude, and altitude. 
3D positioning is more precise than  2D positioning, and it reduces 
the margin of error in the vehicle location display.

Further Information
Accuracy & error calculation
Regarding Precision Accuracy
Since the GPS satellites are controlled by the US Depar tment of Defense 
they do have a very high level of  accuracy, however a multipath due to 
reflections from buildings and so  on could cause errors to occur.
Regarding the Properties of the GPS Electro-
Magnetic Waves and Signal Reception
If there are any obstacles between the GPS antenna and the GPS 
satellite, electromagnetic-waves cannot be received from the satellite.
It is also impossible to use GPS posi tioning in the following locations as 
at least three simultaneous electr omagnetic-waves are necessary to 
take measurements.
Also, if there are any obstacles around the GPS antenna, 
electromagnetic-waves cannot be  received from the satellite.
• In tunnels • If the immediate area is enclosed by 
large objects such as skyscrapers

Further Information
NOTE•Because the GPS satellite is in orbit around the earth, the reception status for 
the electromagnetic waves changes depend ing on their position at that point 
in time, even if your vehicle is in th e same place. Also, electromagnetic-waves 
from satellites near the horizon can be  easily influenced by surrounding 
obstacles.
• At times, satellites under the control of the US Department of Defence will 
intentionally drop positioning accuracy.
Regarding Errors in Current Position Display
The system displays the vehicle  current position based on GPS 
information and data from various  sensors and road maps. However, 
when the radiowave signals from GPS satellites are weak or when 
signals are received only from two sate llites or less, errors may occur in 
the position. Modifying or adjusting  the system will not prevent these 
errors.
• In underground buil dings and indoor 
parking lots • In places with a lot of overgrown 
trees and so on
• Under elevated roads • Roads at the base of cliffs and caves

Further Information
Regarding Vehicle Position Detection 
Correction Using Map Matching
Map matching is a method of comparing information on the current 
position acquired by GPS and so on,  with the road driven up to that 
point, and correcting the current po sition based on the most likely 
road.
This unit uses information on th e current position combined with 
independent navigation and satellite  navigation and matches it to the 
shape of the road to create the correction.
However, as it cannot avoid the error margins at the current position, 
the current position may shift away from the actual position even when 
correcting using map matching.
Also, the vehicle marker may shift if  the map data and the shape of the 
road being driven on differ.
NOTE
Because it takes a short time for operations  to stabilize just after turning on the 
unit, the vehicle mark may not immediately match the vehicle as it moves. After 
driving for a while, operations stabilize,  and the marker should match the actual 
driving position.
Regarding the Accuracy of the Current Position 
and Route Navigation
As in the following images, an accura te display of the current position 
or route navigation may not be pr ovided, however this is not an 
indication of a malfunction in the un it, but is due to road conditions or 
driving conditions.

running in parallel. • Shows the current position on the 
other road when there is a narrow 
fork in the road.
• Shows the current position on the  road ahead or behi nd when turning 
right or left. • Shows the current position when 
traveling up a steep hill.
