How to detect car navigation problems

Source: Time:2020-01-17 17:14:56 views:

1. No satellite signal is received in the car navigation; 2. There is throttle noise when starting the car; 3. There is noise in the navigation condition
1.Satellite signal is not received by car navigation

When found under navigation, the map satellite will show the "current" location. If the dot on the upper right corner of the display screen interface is red, the car navigation manufacturer indicates that the satellite signal is weak, and you should check whether the navigation antenna is connected from the beginning and whether the orientation of the navigation antenna is correct. The car should navigate in the open and empty local area. You need to be balanced with the ground and face the sky directly to receive the signal.


2. Throttle noise when starting the car

The solution is to install an inductor or filter (power supply) on the host ’s power line BATT, or ground the host ’s casing, such as installing a pillow screen. It may also be disturbed by the signal from the headrest screen, which can break the signal of the headrest screen. Turn on to eliminate disturbance.


3.Noise in navigation

Generally, the engine is caused by the disturbance of the navigation power. The solution is to connect a power filter in series on the yellow line of the navigation terminal socket line of the navigation link to reduce the power disturbance from the engine.


4.Can't play sound

4-1. Check if the system is muted. If "yes" press the MUTE key to mute the sound.

4-2. Check if the speaker cable is disconnected. If "yes" connected from the beginning.

4-3. Check whether the speaker is damaged. If yes, replace it with a new one. If the above three conditions are normal, it is generally caused by a short circuit between a certain group of speaker wires and the car body. If all the speaker wires can be disconnected, a good speaker can be connected by itself. If the sound is normal, it means that a group of speakers is in between. The speaker wire is short-circuited. If it is not, the main unit is faulty.


5.DVD is silent

When there is no sound when playing the disc (both normal playback under radio and navigation conditions), you have set the wrong setting for DVD playback. You should go to the "DVD Settings" item of the settings and select "Audio Settings" and enter the "Audio Output" settings. Set it to "Analog Output" and then exit the setting to return to the homepage. The DVD sound will recover normally.


6.Bluetooth pairing settings

6-1. To use the Bluetooth hands-free function, a connection must be established first, and the host and the Bluetooth mobile phone must be paired. Switch the unit to the Bluetooth screen to enter the Bluetooth connection status.

6-2. Turn on the Bluetooth function of your mobile phone and launch the Bluetooth device search function. At this moment, the screen will show “Pairing”. When the system and the mobile phone get the signal connection, the mobile phone will show the title of the device Carkit. When the mobile phone is connected, the mobile phone prompts for the device pairing password: "0000", the pairing is successful, and the host shows Connect ok.

6-3. You can directly pull the number through the mobile phone or enter the phone number through the number buttons on the screen.

6-4. Press the number buttons on the screen to enter the number. The number entered will appear in the number column. If you make a mistake, you can click "Delete" to delete it bit by bit.

6-5. When an external call comes in, the system will actively switch to the Bluetooth function interface in any form to complete the hands-free function, and you can make or receive calls directly.


7.U disk / SD card playback

7-1. To play a file in a USB flash drive, first pierce the USB flash drive with the signal source into the USB interface on the panel of the host computer directly or through a cable.

7-2. To play the files in the SD card, the SD card with the signal source recorded will be inserted directly into the SD card socket on the panel of the host in the correct way.

7-3. After the U disk / SD card is read out, it is the same as the MP3 / MP4 disc playback format.


8. TV has fewer TV stations and is not good

First, make sure that the TV antenna power cable and signal receiving cable are plugged in properly, and the TV production system is selected correctly (for TV functions). It is recommended that the TV antenna be installed on the back glass and used in the open air for better results.


9, positive method of touch screen effect

After the main unit is powered on, enter the radio status, use the broadcast controller to press and hold the "setup" button to enter the proofreading status, use the touch pen to cross the "ten" cross point, and then return to the radio status to complete the proofreading.


10.Back view without rear view painting

First, check whether the host's reverse control cable (orange, yellow, blue) is connected to the rear-view input socket of the host according to the reverse lamp line and the video cable of the rear view camera. (Check whether the trailing line is OK, etc.).


11.Can't boot

This problem is usually caused by a customer's misoperation. The system is temporarily unavailable. Use a toothpick to lightly press the reset button (RET) on the panel and move it from the hair.


12.Can't enter navigation (cannot find navigation software)

Check whether the navigation setting path is OK, or set the navigation software path from the beginning (open the NAVIONE.EXE file in the SD folder NAVIONE folder).


13.Bluetooth sound is low / the other party hears low sound

Please check whether the front speaker channel is well connected. In this system, Bluetooth can only make sounds from the front speaker. The other party cannot hear, please check to see if the speaker is driving.
