To fix a phone that is not connecting to a car’s Bluetooth, here are few things to try:

1. Enable Bluetooth: Make sure Bluetooth is turned on both on your car and phone.


2. Pairing Devices: Make sure the device is paired by following the pairing instructions for both the car and the device.


3. Check App Timeout Settings: Make sure app timeout settings on the device are set for a long enough time before it disconnects from Bluetooth.


4. Phone Settings: Some phones may require special settings to allow Bluetooth to work.


5. Software/Firmware Update: Make sure your car’s Bluetooth system and your phone are using the most recent updates.


6. Perform a Reset: Unpair both devices, and then pair them again to see if that resolves the issue.
