Why is there no sound when playing music via Bluetooth in the Buick Excelle?

[TravisLynn]

The reason there is no sound when playing music via Bluetooth in the Buick Excelle is that the audio source has not been switched to Bluetooth. Only by selecting Bluetooth as the audio source can the music be played. It is recommended that the owner select the audio source in advance before connecting to Bluetooth. The Excelle is a new high-end mid-size car launched by Shanghai GM's Buick brand based on the "global platform, European and American technology," incorporating the dynamic genes that Buick can bestow on a mid-size car. The 2018 Excelle features a new family-style winged chrome grille, giving the front fascia a sharper and more rugged appearance. The combination of black piano vertical grille and high-gloss chrome winged grille naturally draws the visual focus of the front end to the emblem.
