1. The on-board navigation did not receive satellite signal

When it is found that it is in navigation, the map satellite will flash the "then" location. The on-board navigation manufacturer assumes that the dot in the upper right corner of the flash screen interface is red, which indicates 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 receiving 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 is also possible to string interference from the head restraint screen signal. The interference can be eliminated by disconnecting the head restraint screen signal.

3. There is noise during navigation

It is generally caused by the interference of the initiator from 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 connection to reduce the interference of the power supply from the initiator.

4. No news can be broadcast

4-1. Check whether the system is silent. Assuming "yes", press mute to turn off mute.

4-2. Check whether the horn connection has been disconnected. Suppose "yes" is connected from the beginning.

4-3. Check whether the horn is damaged. Assuming "yes", replace it with a new one. Assuming that 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, it indicates that a group of horn wires are short circuited. If not, it is proved that the main engine has hair disease.

5. DVD has no movement

When there is no movement of the broadcast disc (it can be played normally under the conditions of radio and navigation), it is an error in the 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 movement will return to normal.

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 automatically enter the Bluetooth connection.

6-2. Turn on the Bluetooth function of your mobile phone and initiate the Bluetooth device search function. At this time, the screen flashes "pairing". When the system gets the signal connection with the mobile phone, the name carkit of the device flashes at the hand. When connecting, the mobile phone prompts the device pairing password: "0000", the pairing is successful, and the host flashes connect OK.

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

6-4. Press the number button on the screen to enter the number, and the entered number will flash in the number column. If the input error is found, click "delete" to delete it bit by bit.

6-5. When an external call comes in, under any method, the system will automatically 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 broadcasting

7-1. To broadcast 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 according to the correct method.

7-2. Broadcast 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 according to the correct method.

7-3. After the USB flash disk / SD card is read out, it is the same as MP3 / MP4 disc broadcasting method.

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 situation, press the "setup" button with the broadcast controller to enter the correction situation, and use the contact pen to align the cross point of the "cross" frame until the radio situation returns automatically to complete the correction.

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) 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 the beginning (just open the navione.exe file in the NAVIONE folder of SD folder).

13. Bluetooth is quiet / the other party hears little

Please check whether the front horn channel is connected properly. The system plans that Bluetooth can only move through the front horn. If the other party can't hear it, please check whether the speaker is in the driving position.
