What are the reasons for sudden Bluetooth connection failure in BMW?

[LaJanelle]

Most BMW vehicles are equipped with Bluetooth functionality, allowing connection with external Bluetooth devices for music playback, phone calls, and other features. When the device malfunctions, it may lead to Bluetooth connection failure. Relevant information about in-car Bluetooth is as follows: 1. Function: After successful Bluetooth pairing, you can use your phone to play audio files or answer calls, which is very convenient. While driving, it ensures road safety. Once the car's infotainment system is connected to the Bluetooth system, you can make calls directly through the infotainment system in hands-free mode. 2. Automatic connection: After the initial connection between the phone and the car's system, subsequent uses will automatically connect, provided the phone's Bluetooth is turned on. This eliminates the need for frequent reconnections, saving time and adding convenience to vehicle use. However, when using Bluetooth calls, privacy should be taken into consideration.
