How to fix connection problems with the Bluetooth hearing aids in the car?
If the car is equipped with a Bluetooth system which was previously paired to the phone, it could try to connect every time one enters the car. This may result in a connection loss to the hearing aids since the phone can only have one connection at a time.
The exact behavior depends on the version and configuration of the car’s Bluetooth system. To prevent unwanted switching, consider removing the car’s Bluetooth system from the list of paired devices via the phone’s configuration screen.
