NAVIGATION SYSTEM
GPS (Global Positioning System) is developed for and is controlled
by the US Department of Defense. The system utilizes GPS satel-
lites (NAVSTAR), sending out radio waves while flying on an orbit
around the earth at an altitude of approximately 21,000 km.
The receiver calculates the travel position in three dimensions (lati-
tude/longitude/altitude) according to the time lag of the radio waves
that four or more GPS satellites transmit (three-dimensional position-
ing). The GPS receiver calculates the travel position in two dimen-
sions (latitude/longitude) with the previous altitude data if the GPS
receiver receives only three radio waves (two-dimensional position-
ing). GPS position correction is not performed while stopping the
vehicle.
Accuracy of the GPS will deteriorate under the following conditions:
• In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes.
• The position of GPS satellite affects GPS detection precision. The position detection may not be precisely
performed.
• The position detection is not performed if GPS receiver does not receive radio waves from GPS satellites.
(Inside a tunnel, parking in a building, under an elevated highway etc.) GPS receiver may not receive radio
waves from GPS satellites if any object is placed on the GPS antenna.
NOTE:
• The detection result has an error of approximately 10 m even with a high-precision three dimensional posi-
tioning.
• There may be the cases that the accuracy is lowered and radio waves are stopped intentionally because the
GPS satellite signal is controlled by the US trace control center.

Camera image operation principle
• Power is supplied to rear view camera from camera control unit and outputs camera image signal to camera
control unit when selector lever is set to R position and the reverse signal on camera control unit is input.
• Camera control unit synthesizes guide lines and possible route lines with camera image signal from rear
view camera, and transmits camera image signal to the display. In this case, since the reverse signal is also
input to AV control unit, the AV control unit recognizes the selector lever as in R position, and it switches
communication signal between AV control unit and display unit, and image that is displayed on the display
unit by RGB signal with rear view monitor image. In addition, possible route lines are controlled by original
sensor signal from steering angle sensor.
• The AV control unit determines whether rear view camera is equipped or not, based on the presence of cam-
era connection recognition signal. It switches to rear view monitor image at the time of reverse signal input
when it is not equipped.
• Warning message under the rear view monitor display is described by AV control unit.
• AV control unit is connected in communication with camera control unit and display unit, and it controls oper-
ation of rear view monitor system.
