1. When a Bluetooth car plays a song, it is suspended because of a new car, so the mobile phone is not compatible with the car Bluetooth, which leads to unstable Bluetooth connection, and the Bluetooth connection is stopped or disconnected, so that the music is automatically suspended.

2. Too many records of Bluetooth-connected devices on the vehicle or too many electrical devices on the vehicle will affect the Bluetooth signal reception, which will lead to the automatic suspension of Bluetooth music on the car.
