The reasons for no sound when playing music after successful Bluetooth connection in Buick Excelle are as follows: The volume on the car navigation system or mobile phone is not turned on: Go to "Settings" - "Sound" on the phone, find the "Media" option, and turn up the "Media" volume. The same applies to the car navigation system. The music playback programming of some phones (such as iPhone) does not match the docking code of certain car models: It is recommended to change the Bluetooth playback frequency band to use it normally. Multimedia music is not enabled on the car Bluetooth: Find the multimedia option on the screen, enter it, and select Bluetooth to play music.
Last time my Excelle had the same issue with Bluetooth connection—it showed as connected but no sound when playing music, which was quite frustrating. I found there are three common causes: first, a phone setting issue where the output isn't set to Bluetooth but defaults to the speaker or headphone jack; second, the volume is too low—try increasing both the phone and car audio volumes, and don’t forget to check if it’s in silent mode; third, an app conflict or system bug, where restarting the devices often works—turn off the phone’s Bluetooth and reboot the car’s infotainment system, and it’s usually resolved. If it’s a hardware failure like a faulty Bluetooth module, you can visit a 4S shop for inspection, but such cases are rare. Regular system updates and maintenance can prevent most issues.
