Navigation function inspection

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

Launch the diagnostic assist function. (See ACTIVATION PROCEDURE .)
Select in the following order from the diagnostic assist function initial screen.
1. [Functional Inspection/Adjustment]
2. [Navigation System Inspection]

Verify if the navigation function is operating correctly referring to the following table.

CONTENT AND FUNCTION DESCRIPTION

No.	Name	Indication on center display	Content/function	Action
1	Positioning level	OK (3D)	The connectivity master unit (CMU) receives information from 4 or more GNSS satellites and indicates that 3D positioning is operative.	Inspect the following if the navigation function does not operate correctly. Global Navigation Satellite System (GNSS) antenna or global positioning system (GPS) antenna related DTCs (See DTC TABLE [CONNECTIVITY MASTER UNIT (US)] .) Global Navigation Satellite System (GNSS) antenna or global positioning system (GPS) antenna related symptom troubleshooting (See SYMPTOM TROUBLESHOOTING (US) .) GPS antenna feeder (Refer to [GPS ANTENNA FEEDER INSPECTION] in appropriate service information) Global Navigation Satellite System (GNSS) antenna (Refer to [GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) ANTENNA INSPECTION] in appropriate service information) Wiring harness between Global Navigation Satellite System (GNSS) antenna/global positioning system (GPS) antenna and connectivity master unit (CMU)
		OK (2D)	The connectivity master unit (CMU) receives information from 3 GNSS satellites and indicates that 2D positioning is operative.
		NG	The connectivity master unit (CMU) receives information from only 2 or less GNSS satellites and indicates that positioning cannot be calculated.
		Error	Indicates that a reception error has occurred.
		-	Other
2	GNSS reception number	-	Indicates the number of GNSS receptions up to 12 satellites.
3	2D positioning time	%	Indicates the percentage of time the positioning level indicates that 2D positioning is operative.
4	Positioning level NG time	%	Indicates the percentage of time the positioning level indicates NG.
5	Current position (longitude)	° (deg)'"	Indicates the current longitudinal position in [degrees], [minutes], and [seconds]. NOTE: When position information cannot be acquired, [00° 00' 00"] is displayed.
6	Relative bearing/relative angle reset	Reset Relative Bearing/Relative Angle	Resets the relative bearing and relative angle.
7	GNSS date and time setting	GPS Date/Time Setting	Sets the date and time stored in the connectivity master unit (CMU). NOTE: Change the year, month, day, hours, minutes, and seconds using the left and right arrow buttons, and then select [Completed] to finish the setting.
8	Vehicle speed	km/h	Indicates the vehicle speed.
9	Gyro/distance coefficient learning condition	Courtesy of MAZDA MOTORS CORP.	Indicates that there is no learning regarding the gyro/distance coefficient.
		Courtesy of MAZDA MOTORS CORP.	Indicates that learning regarding the coefficient of the vehicle speed is completed.
		Courtesy of MAZDA MOTORS CORP.	Indicates that learning regarding the sensitivity of the gyro sensor (built into connectivity master unit (CMU)) is completed.
		Courtesy of MAZDA MOTORS CORP.	Indicates that learning regarding the installation angle of the gyro sensor (built into connectivity master unit (CMU)) is completed.
		Courtesy of MAZDA MOTORS CORP.	Indicates that the learning regarding the offset of the acceleration sensor (built into connectivity master unit (CMU)) is completed.
10	Relative angle	° (deg)	Indicates the relative angle.	Inspect the following if the navigation function does not operate correctly. Global Navigation Satellite System (GNSS) antenna or global positioning system (GPS) antenna related DTCs (See DTC TABLE [CONNECTIVITY MASTER UNIT (US)] .) Global Navigation Satellite System (GNSS) antenna or global positioning system (GPS) antenna related symptom troubleshooting (See SYMPTOM TROUBLESHOOTING (US) .) GPS antenna feeder (Refer to [GPS ANTENNA FEEDER INSPECTION] in appropriate service information) Global Navigation Satellite System (GNSS) antenna (Refer to [GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) ANTENNA INSPECTION] in appropriate service information) Wiring harness between Global Navigation Satellite System (GNSS) antenna/global positioning system (GPS) antenna and connectivity master unit (CMU)
11	Relative bearing	° (deg)	Indicates the relative bearing.
12	Vehicle turning angle speed	deg/sec	Indicates the turning angle speed of the vehicle.
13	Current position (latitude)	° (deg)'"	Indicates the current latitudinal position in [degrees], [minutes], and [seconds]. NOTE: When position information cannot be acquired, [00° 00' 00"] is displayed.
14	Current date and time	YYYY/MM/DD hh/mm/ss	Indicates the current date and time stored in the connectivity master unit (CMU).
15	3D positioning time	%	Indicates the percentage of time the positioning level indicates that 3D positioning is operative.

Ends the diagnostic assist function. (See ENDING PROCEDURE .)
