Introduction
Navigation System
This navigation system utilizes GPS* satellite signals, 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.
This DVD Navigation System combined with the NAVTECH's MAP Disc
has following special features:

Detailed maps are used.
Selected destinations will be displayed for easy viewing.

Desired places or facilities can be stored in the memory.
Features

DVD audio and video will not work by this unit.

This unit does not support all Video CD and CD formats.
Notes
Use This Product Safety
Do not expose the product to water or excessive moisture.
This could cause electrical shorts, fire or other damage.
Avoid excessive moisture
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 Mazda Dealer.
Extremely low or high temperatures may interfere with normal operation

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.

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
turning on the ignition.
GPS signal reception is poor in the following places
In tunnelsAmong high-rise buildingsUnder elevated roads In wooded areas
GPS
Map Matching
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 RoadsPosition accuracy is improved by detecting if
the vehicle is running on or under an elevated road.

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.
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.
Position Correction for Parking GaragesPosition accuracy is improved by detecting if the vehicle
is driving in an elevated or underground parking garage.
High-precision GyrosensorA 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.
