Here are the reasons and solutions for low volume in Corolla's car Bluetooth phone: Mismatched Bluetooth versions between car and phone: Check if the car's Bluetooth system version is compatible with your phone's Bluetooth version, as version incompatibility may cause abnormalities. Car Bluetooth malfunction: Verify if the car Bluetooth is functioning properly. Check for any car Bluetooth faults that might cause connection issues with the phone. Try connecting other phones to the car Bluetooth to see if normal function is restored. Phone Bluetooth malfunction: Test your phone's Bluetooth by connecting it to other cars or phones. If the Bluetooth is malfunctioning, back up your data and perform a factory reset. If the issue persists, it's recommended to take your phone along with the purchase invoice and warranty card to a local service center for inspection and repair.
Regarding the issue of low volume on the Corolla's Bluetooth calls, I think there are quite a few possibilities, mainly related to settings or hardware. It's quite common that the Bluetooth audio volume on the phone isn't turned up high enough—make sure to push the phone's volume buttons to the maximum before each call. There can also be issues with the car's infotainment system; look for the Bluetooth audio option in the settings menu, as the default level is sometimes too low, and manually increasing it can help. Additionally, the Bluetooth module itself might have bugs or need a firmware update—try connecting it to a computer to upgrade the software. Another possibility is that the car's speakers are dusty or have poor contact; regularly cleaning the connectors can improve signal transmission. Environmental factors also play a role; too many electromagnetic interference sources nearby, such as phone chargers, can reduce the volume. In short, troubleshooting these points can resolve most situations.
