How to detect the problem of vehicle navigation fault
1. The navigation system did not receive the satellite signal
When it is found that it is under navigation, the map satellite will show the "current" location. If the dot in the upper right corner of the display screen interface is red, the on-board navigation manufacturer illustrates that the satellite signal is weak. It should check whether the navigation antenna is connected and whether the orientation of the navigation antenna is correctly placed from the beginning. The car should navigate in the open air and open place. The antenna should be balanced with the ground and directly face the sky before it can receive the signal.
2. There is throttle noise when starting the car
The solution is to install an inductor or filter (power supply) on the host power line batt, or ground the host shell. If a pillow screen is installed, it may also string interference from the head restraint screen signal. The interference can be eliminated by disconnecting the head restraint screen signal.
3. There is noise under navigation
Generally, the engine is disturbed by the navigation power supply. The solution is to string a power filter on the yellow line of the navigation terminal socket line of the navigation terminal wiring to reduce the power disturbance from the engine.
4. No sound can be played
4-1. Check whether the system is silent. If "yes", press mute key to turn off mute.
4-2. Check whether the horn is disconnected. If "yes", connect from the beginning.
4-3. Check whether the horn is damaged. If "yes", replace it with a new one. If the above three items are normal, it is generally caused by a short circuit between a group of horn wires and the vehicle body,
When all the horn wires can be disconnected, connect a good horn alone. If the playback is normal, explain that a group of horn wires are short circuited. If not, it is proved that the host is faulty.
5. DVD silent sound
When there is no sound in the playing disc (it can play normally under the conditions of radio and navigation), it is the fault of DVD playback setting. You should enter the "DVD setting" item set, select "audio setting", enter the "audio output" item set to "analog output", and then exit the setting to return to the home page. The DVD sound will recover normally.
6. Bluetooth pairing settings
6-1. To use the Bluetooth hands-free function, you must first establish a connection and pair the host with the Bluetooth mobile phone. Switch the machine to the Bluetooth screen to actively enter the Bluetooth connection status.
6-2. Turn on the Bluetooth function of your mobile phone and start the Bluetooth device search function. At this moment, the screen shows "pairing". When the system is connected with the mobile phone, the mobile phone will display the title carkit of the device. When connecting, the mobile phone will prompt for the device pairing password: "0000", the pairing is successful, and the host will display connect OK.
6-3. You can dial the number directly through the mobile phone or enter the phone number through the number button on the screen.
6-4. Press the number button on the screen to enter the number, and the entered number will appear in the number column. If the input is wrong, click "delete" to delete it bit by bit.
6-5. When an external call comes in, in any form, the system will actively switch to the Bluetooth function interface to complete the hands-free function, and can make or receive calls directly.
7. USB flash disk / SD card playback
7-1. To play the files in the USB flash disk, first insert the USB flash disk with the signal source into the USB interface of the host panel directly or through the adapter cable in the correct way.
7-2. Play the files in the SD card and insert the SD card with the signal source directly into the SD card socket of the host panel in the correct way.
7-3. After reading out the USB flash disk / SD card, it is the same as MP3 / MP4 disc playing mode.
8. Less TV reception and poor performance
First, confirm whether the TV antenna power line and signal receiving line are plugged in properly, and the TV manufacturing system is selected correctly (for functions with TV). It is recommended that the TV antenna be installed at the place pasted with glass at the back, and the effect is better when it is used in the open air.
9. Contact screen effect correction method
After the host is turned on, enter the radio status, press the "setup" button with the broadcast controller to enter the proofreading status, and use the contact pen to align the cross point of the "cross" character frame until you come back to the radio status and complete the proofreading.
10. There is no rear view painting for reversing
First, confirm whether the reversing control line (orange, yellow and blue) of the host is connected with the rear view input socket of the host according to the reversing lamp line and the rear view camera video line. (check whether the tail line is connected, OK, etc.).
11. The machine cannot be started
This problem is generally caused by the customer's misoperation. The system can't work temporarily. Use a toothpick to gently press the panel reset key (RET) and move it from the hair.
12. Unable to enter navigation (unable to find navigation software)
Check whether the navigation setting path is OK, or set the navigation software path from scratch (just open the navione.exe file in the NAVIONE folder of SD folder).
13. Bluetooth makes little noise / the other party hears little noise
Please check whether the front speaker channel is connected properly. This system plans that Bluetooth can only make sound from the front speaker. If the other party can't hear it, please check whether the speaker is in the driving position.
