Yes, it does. In the 'Settings - Sound Output - Dual BT (Display only)' mode on the device, the screen only receives interconnected imagery from the phone and does not participate in sound output. In this mode, the phone's sound is independent; when playing music, the sound comes from the phone's speaker, and when the phone is connected to the car's Bluetooth, the car plays the sound, just as it would with regular phone use. The phone can normally connect to the car's Bluetooth to play stereo sound, supporting maps, music, and phone call audio through the car's sound system. Calls are handled using the car's original microphone, and the system also supports the car's multifunction steering wheel controls. The phone can connect to multiple Bluetooth devices simultaneously, and the advantage of this mode is that Bluetooth audio output from the phone has less latency in sound transmission compared to wireless CarPlay for music. The device is set to 'Display only' mode by default. If this mode is turned off, sound will be emitted through the device, and the microphone will use the screen's integrated microphone for audio pickup.
