Why does the car Bluetooth display show A2DP not connected?
2 Answers
Reasons for the car Bluetooth display showing A2DP not connected are as follows: Unstable Bluetooth performance: The Bluetooth systems installed in different car models vary, and some models have relatively unstable Bluetooth performance, which may cause Bluetooth lag during the connection process, thus failing to connect to A2DP. In this case, simply turn off the Bluetooth and reconnect. Media audio not enabled: Some car models' Bluetooth systems have two buttons in the connected Bluetooth settings: "Call audio" and "Media audio." If the media audio is not enabled, the Bluetooth can only be used for calls but not for playing music, and the system will also prompt this. Device damage: If after restarting the device or re-pairing the Bluetooth, it still shows A2DP not connected, it is likely due to device damage. In this case, the device needs to be inspected and repaired.
I've encountered this issue several times, and it's usually related to mobile phone settings. First, check if there are two car device names in your phone's Bluetooth list - you might be connected to the basic call protocol only. Pay special attention to whether the A2DP option is checked in your phone's Bluetooth settings. Nowadays, Huawei and Xiaomi phones often automatically disable this permission. A friend of mine had the same problem with their car audio system, which turned out to be caused by permission reset after a phone update. Another solution is to disconnect all devices in the car first, restart the car's infotainment system, wait 10 seconds, and then reconnect. Sometimes the system acts up when its cache is full. If all else fails, try testing with another phone. If other phones work fine, then it's definitely your phone's system issue. Don't rush to the 4S shop - you can probably solve it yourself.
