How to solve the problem of no sound in navigation, and what is the problem of no sound in navigatio

The solution to no sound in navigation is as follows;

1. **The volume is not turned on.

Try dialing a ** number. On a dial or call, press the volume button on the side of the car to turn up the sound to the maximum. Of course, you can also go directly to your phone's settings, find the Sound** option and turn it up.

2. The volume of the integrated car navigation device is not turned on.

If you find that there is no sound in navigation, you can check whether the volume adjustment on the panel of the all-in-one car navigation system is turned on. If you didn't tap Settings on the screen, find the Volume button and turn on Volume. It is also possible that the owner has turned on the FM transmitter function, so as long as you enter the FM transmitter function interface and turn it off.

3. The pairing of the car Bluetooth and the mobile phone is unsuccessful.

Under normal circumstances, we only need to establish the pairing relationship between the mobile phone and the car Bluetooth, turn on the Bluetooth function of the mobile phone and the car Bluetooth device respectively, set the Bluetooth of the mobile phone to "visible to everyone", and then search for the Bluetooth device in the mobile phone, and pair and connect after finding it. The pairing password is 0000, and the connection is successful after the pairing is completed.

Due to the instability of the electronic device, it may sometimes not be possible to connect to the car's Bluetooth. At this point, we can try to turn off some of the electrical equipment in the car and try to reconnect.

I guess you inadvertently turned on the navigation sound. When navigating the broadcast, the sound will be quieter. So, while you suddenly become quieter, adjust the volume of the small knob, and the navigation is being broadcast at this time.

There are three reasons why there is no sound in navigation.

First, you can check if the navigation sound is turned on or if you have silent mode enabled.

Second, you can check the FM emission of the navigation, whether it is turned on, if it is hit, the navigation is not sound, you need to turn it off so that the navigation can have sound.

Third, it may be that your navigation horn is broken, you can go to the counter you bought or ask ** to send the machine to them.

Reasons: 1. The first use of navigation needs to be activated by the network to use the voice broadcast function.

2. It is possible that the navigation has not been activated online. If you want to activate the network, you must first exit the navigation, then connect to the network, and then restart the navigation software, it will be automatically activated, and the voice broadcast function can be used normally.

3. There may also be such a problem: some friends may set their mobile phones to silent mode, or the volume of their mobile phones is turned to the lowest, so there is no sound for navigation. Just change the mode or turn up the volume to solve the problem.

4. As for the problem that the navigation cannot make sound due to the use of Bluetooth headsets, there may be slight differences between different brands of mobile phones, and you can explore how to use it.

The horn is short-circuited, the sound file is problematic, it may be installed incorrectly, the sound switch is not turned on, that is, there is no navigation system for language navigation, and there is no driver for the sound hardware.

Set the volume in the car system, press and hold the volume + in the navigation interface, regardless of whether the volume has been displayed at the maximum, see if there is any sound, in some cases, the navigation CD fails after installation and there is no sound, you can go to the 4S shop to find a professional repair.

Vehicle-mounted navigation host installation requirements.

Before installing the car navigation, check whether the function display of the car dashboard and the buttons in the car are normal, whether there is any mess on the inside and outside of the car, and in the process of installing the car navigation, the removed auto parts should be placed to avoid scratching the dashboard in the car and protect the objects in the car. Dispose of the debris left behind during wiring in time and do not leave it in the car. The joints must be insulated to prevent short circuits.

The wiring should be reasonable. The installation space in the car is relatively small, so try to minimize unnecessary wires, reduce the space occupied, and make the car navigation host easy to install.
