Why is there no sound when playing music after successfully connecting Bluetooth in Cruze?

In this case, re-pairing is required. The reason is that an abnormality occurred during the pairing process, which is not considered a fault issue. Before re-pairing, you need to turn off and then turn on your phone, and also turn off and then turn on the vehicle's multimedia system. This should resolve the issue. Relevant information about car Bluetooth is as follows: 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 driving safety. Once the car's system and Bluetooth are connected, you can make calls directly through the car's system in hands-free mode. Automatic Connection: Once your phone and car system are connected, they will automatically connect the next time you use them, provided that your phone's Bluetooth is turned on. This eliminates the need for frequent manual connections, saving time and adding convenience to vehicle use. However, when using Bluetooth calls, be mindful of privacy.

My old Cruze had the same issue - the Bluetooth showed connected but no sound came out. Turning the phone volume to max didn't help. Turned out it was the infotainment system problem where the multimedia volume was defaulted too low. You need to find the volume settings on the center display and specifically increase the Bluetooth media volume, as adjusting just the call volume won't work. Sometimes it's also about phone permissions - Android systems tend to disable media output, so check device permissions in Bluetooth settings. Restarting both the infotainment system and phone solves half the problems, as Cruze's system occasionally acts up. If it still doesn't work, the Bluetooth module might be outdated, especially for pre-2015 models which often develop compatibility issues over time. Don't worry, just troubleshoot step by step and you'll fix it eventually.

Having played with digital gadgets for over a decade, I've mastered the Cruze Bluetooth issues. First check if your phone's audio output is set to speaker instead of car audio—for iPhone, long-press the music widget in Control Center to select device; for Android, adjust in Bluetooth settings. In the car, press the SRC button to switch to Bluetooth audio source—sometimes it automatically jumps to radio. Then check the mute button, as the steering wheel or center console mute button might be accidentally pressed. There's also the app permission issue—like QQ Music refusing to transmit sound via Bluetooth right after an update. Worst case is hardware failure—the Bluetooth module is located behind the glove box on the passenger side, and I've seen cases where the connector came loose. Restoring the car stereo to factory settings can refresh the connection protocol—this trick works wonders.

Just helped my neighbor with this last week. First, check if the car's infotainment system hasn't authorized media audio. The Cruze will pop up three permission boxes during pairing: calls, media, and contacts. Many people only check the call option, resulting in phone calls working but no music sound. Then check your phone's media volume - you need to turn up both the phone and car audio volume simultaneously. Another common pitfall is when the phone's music app acts up; switching to a different music app often solves it immediately. If charging via cable, unplug it and try again - current interference can be surprisingly problematic. Finally, check if external audio output is disabled in the vehicle settings; you'll find this option tucked away in a corner of the sound menu.
