How to set the navigation without sound?

There is no sound in navigation. You can check whether the volume of the mobile phone is turned on, whether the volume of the navigator is turned on, and whether the car Bluetooth and the mobile phone are not paired successfully.

1, the phone volume is not turned on.

Try to dial a phone number. When dialing or talking, press the volume button on the exit side to turn the sound to the maximum.

Of course, you can also go directly to the phone settings, find the sound media option, and turn up the volume.

2. The volume of the car navigator is not turned on.

If there is no sound in navigation, you can check whether the volume adjustment on the multi-function car navigator panel is turned on. If you didn't click Settings on the screen, find the Volume button and turn on the media volume.

It is also possible that the owner has turned on the FM launch function, and just enter the FM launch function interface and close it.

3. The pairing of the car Bluetooth and the mobile phone was 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 all", then search for the Bluetooth device in the mobile phone, and then make pairing connection after finding it. The pairing password is 0000, and the connection is successful after the pairing is completed.

Due to the instability of electronic equipment, it may sometimes be impossible to connect the car Bluetooth. At this time, we can try to turn off some electrical equipment in the car and try to reconnect. In addition, Bluetooth devices have compatibility problems, or there may be pairing records of other devices on the mobile phone. When the pairing fails, it is suggested to delete the original pairing and reconnect.

If none of the above methods can solve the problem, it may be that the mobile phone system has not been updated to the applicable version, or there is something wrong with the navigation software version. Suggest updating or deleting, and try again next time.
