Why is there no sound from the car navigation system?
2 Answers
Reasons for no sound from the car navigation system: 1. The volume setting in the navigation system is not turned up or the mute setting is turned on; 2. The media audio on the phone is not turned off, causing signal interference with the Bluetooth function. First, enter the Bluetooth settings interface on the phone, turn off the media audio, and keep the phone audio; 3. The speaker wire is broken or damaged, just replace the wire or the speaker; 4. Generally, the sound of the mobile navigation software is defaulted to the mobile audio output, which causes the sound of the car navigation system to come from the phone during use. Just select the media audio channel in the car Bluetooth channel of the mobile navigation.
Yesterday I just encountered the issue of no sound from navigation. First, check if the volume buttons on the steering wheel were accidentally pressed to mute. Then, verify whether the media volume and navigation volume in the infotainment system settings were turned down to the minimum. Next, try playing in-car music—if other functions have sound but navigation remains silent, it's most likely a navigation software bug. In this case, restarting the infotainment system is the most effective solution. When connected via Bluetooth, pay special attention to the phone priority issue, as it sometimes automatically switches to phone announcements. On the software side, long-pressing to clear navigation cache or updating map data can also be quite helpful. If that doesn’t work, check for loose wiring connections, especially in cars with aftermarket infotainment screens, as they are prone to poor contact. Don’t rush to the repair shop—spending ten minutes troubleshooting can usually resolve it yourself.
