What Causes No Sound When Playing Music via Bluetooth Connection Between Phone and Car?
2 Answers
The reasons for no sound when playing music via Bluetooth connection between phone and car are: 1. The volume on the car navigation system or phone is not turned on; 2. Some phones' music playback programming is incompatible with the car model's pairing code; 3. The multimedia music feature of the car's Bluetooth is not enabled; 4. The media audio on the phone is not turned off, causing signal interference with the Bluetooth function. The solution to no sound when playing music via Bluetooth connection between phone and car is: Enter the Bluetooth settings interface on the phone, where there are two options: phone audio and media audio. After connecting to the car's Bluetooth, both options are enabled by default. You need to turn off the media audio and keep the phone audio, which ensures that the three functions—Bluetooth calls, car music playback (or radio), and phone navigation announcements—do not interfere with each other.
It's really annoying when the phone connects to the car via Bluetooth but there's no sound. I've encountered this issue several times. The most common reason is that the car's multimedia system isn't switched to Bluetooth mode, still stuck on radio or USB. The phone's volume might be muted, or the music app settings could be incorrect. Successful Bluetooth pairing doesn't guarantee audio functionality - sometimes it's due to outdated Bluetooth versions on the phone being incompatible with the car system. Try restarting both the phone and car multimedia system, then toggle Bluetooth off and on to reconnect. If nothing works, there might be an issue with the car audio system or external interference causing signal drops. My personal troubleshooting routine: first check volume buttons, then verify Bluetooth is selected as input source on the car interface, and finally reconnect - this usually does the trick.
