There is no sound when motorcycle positioning sends information.

1. The volume setting in the navigation system is not turned up, or the mute setting is turned on. The FM launch function interface opens the FM launch function. If other navigation sounds are normal, it is a navigation system version problem.

2. The media audio on the mobile phone is not turned off, resulting in signal interference in the Bluetooth function. First of all, you should enter the Bluetooth setting interface of your mobile phone, turn off the media audio and keep the mobile phone audio.

3. There is a horn to play sound, and the horn line is broken or broken, so there will be no sound. If you change the line or change the horn, there will be sound in navigation.

Generally speaking, the voice of mobile navigation software is output to the mobile phone audio by default, which also causes the voice of car navigation to come from the mobile phone when it is used.

The solution is to select the media channel from the car Bluetooth channel in mobile navigation.
