Reasons for no sound when playing music via Bluetooth connection between the car and phone: 1. The call volume on the phone is not turned on; 2. The volume on the car navigation system is not enabled; 3. The car Bluetooth and phone are not properly paired. The Bluetooth technology in car Bluetooth systems is derived from mobile phone Bluetooth technology, sharing the same transmission system, and is a wireless hands-free system designed for in-car use based on wireless Bluetooth technology. How to use car Bluetooth: 1. Turn on both the phone and car Bluetooth, search for the car Bluetooth BYDAOUT (this is generally the default name), then connect and set it to auto-connect for automatic connection when entering the car; 2. Set and enable phone music in the multimedia system, then return; 3. Select phone music from the multimedia home interface and click play.
I've encountered the issue of no sound when connecting my phone to the car's Bluetooth several times. First, check if your phone volume is turned down too low - many people mute media volume when using navigation. Also try adjusting the car's volume knob, as some models have separate controls for music and calls. Check the paired devices list to see if two devices are connected simultaneously - sometimes the car system stupidly stays connected to your wife's phone. The most troublesome issue is Bluetooth channel conflicts - last time I fixed it immediately by turning off my dashcam's wireless function. If all else fails, try factory reset by holding the steering wheel phone button for 10 seconds to reconnect. Oh, and don't forget to open your phone's music app - it's common for the track change button to work but no playback occurs.
Recently, many people have been asking me about the issue of no sound when playing music via Bluetooth. I've identified several key points: Check in the phone's Bluetooth settings whether the car system connection status shows 'audio enabled'—Apple phones are particularly prone to this bug. Ensure the media source on the car's screen is switched to the Bluetooth option, and see if the song change buttons on the steering wheel can bring up the menu. For Android systems, changing the Bluetooth decoder from AAC to SBC in the developer options can resolve compatibility issues. If the car's microphone has a red light on, it means it's in call mode; you need to hang up the call to play music. For used cars, pay attention to the device limit set by the previous owner—clearing the pairing history in the system settings can be very helpful. In winter, the car system may respond slowly; waiting a couple more minutes might bring back the sound.
Elderly people often encounter no sound when using Bluetooth. Here's how I taught my neighbor to handle it: Open the phone settings and tap on Bluetooth, find the small gear icon next to the car's name, and toggle the media audio switch back on. Look for a button with a musical note icon in the car, as many vehicles have a separate control for the multimedia switch. Check the dashboard for a phone symbol; if present, long-press the hang-up button on the steering wheel. Have younger people help upgrade the car's infotainment system, as older versions are prone to disconnections. Most importantly, turn off the phone's hotspot, as wireless frequency conflicts can cause significant issues. Finally, test if a Bluetooth headset connected to the phone produces sound; if there's still no sound, the problem likely lies with the phone.
