My car also had the issue where Bluetooth playback would stop after 30 seconds, and it took me several days to fix it. At first, I thought it was a phone problem, but even after switching phones, the issue persisted—it was definitely a problem with the car's system. I checked the Bluetooth connection status and found that it was more likely to drop in areas with weak signals, possibly due to issues with the phone or car settings. Turning off the phone's power-saving mode didn’t help. Later, I reset the car’s system to factory settings and re-paired the devices, but it still occasionally disconnected. I suspected the car’s Bluetooth module was overheating or had a poor antenna connection. Moving other electronic devices like the GPS away reduced some interference, but it wasn’t a permanent solution. Finally, I took it to the 4S shop, where the technician said a loose wiring connection was the culprit—simply plugging it back in tightly fixed the issue. They advised being mindful of bumpy roads while driving. For future troubleshooting, start with software and hardware settings to avoid unnecessary expenses.
