Introduction
■Extremely low or high temperatures may interfere with normal operation.The inside of the vehicle can become very hot or cold when it is parked for extended
periods in direct sunlight or in cold places with the engine turned off. The navigation system
may not operate normally under such circumstances. Turn off the navigation system until
the inside of the vehicle has cooled down or warmed up. If the system does not operate
thereafter, consult an Authorized Dealer, we recommend an Authorized Mazda Dealer.
This navigation system utilizes GPS* satellite signals, a speed sensor and gyrosensor to track
and display your vehicle’s current position, and to guide you from your starting point to your
destination along a calculated route.
* : GPS (Global Positioning System) is a position detecting system utilizing the signals from GPS satellites deployed by the U.S. Defense Department.
Screens displayed in this manual may differ from those on the actual display.
Direct sunlight or other outside light sources make it difficult to view the images on the display.
For moonroof-equipped vehicles, close the sunshade to better view the display.

GPS is a position detecting system utilizing the signals
from GPS satellites deployed by the U.S. Department of
Defense. The Mobile Navigation System uses input from
three or more satellites and calculates the vehicle position
based on the principle of triangulation.
The positioning accuracy of the system corresponds to the
error display of the GPS which is from about 30 to 200 meters
(98 to 656 ft)
.
● If you are using the system for the first time, or if you have not used it for some time, it takes
about 5 minutes (or about 2 minutes in open areas) to calculate your vehicle’s position.
■GPS signal reception is poor in the following places.
●The GPS satellites are controlled by the U.S. Defense Department, which may intentionally
lower positioning accuracy. In such cases, there may be vehicle position deviations.
● There may be vehicle position deviations for some time until GPS signals are received after
the ignition is switched ON.
This function compares your vehicle’s tracking data with the road data on the map
disc, applies dead reckoning to determine the road you are driving on, and displays
your vehicle on that road on the map.
● Intelligent map matching addresses the following problems to achieve high accuracy in
vehicle positioning.
Position Correction for Elevated Roads.Position accuracy is improved by detecting if the vehicle is
running on or under an elevated road.
Position Correction for Parking Garages.Position accuracy is improved by detecting if the vehicle is
driving in an elevated or underground parking garage.
High-precision Gyrosensor.A gyro detects turns with an accuracy of 0.05° per second.
Combined with a speed sensor, it enables the system to
display the current vehicle position even where GPS signals
may be blocked.
● Using a spare tire in place of the regular one may cause vehicle position deviations.
● Any difference between the direction which your vehicle actually travels and that shown on
the map is automatically eliminated by azimuth correction.
