In the event of problems with connection via Bluetooth-connected phone
If you experience difficulties when connecting a phone to the car via Bluetooth
- Check that the phone battery is sufficiently charged and that the phone is switched on.
- Check that you have Bluetooth switched on in both the phone and the car.
- Check that you have established a Bluetooth connection and have connected the car to the phone to be used.
- If possible, try to connect another phone to the car via Bluetooth in order to check whether the problem is in the device or in the car.
If the problem persists:
- Clear all previously added phones in the Bluetooth settings in the car.
- Restart the phone you want to connect.
- Try to connect the phone again.
In the event of problems with connection via the car's built-in modem1
If connection via the car's built-in modem works poorly due to poor coverage, for example, try connecting via Wi-Fi networks or Bluetooth-connected phone instead.
Note
If you connect to the Internet through several different sources at the same time, such as if the car has Internet via built-in modem, and you access the Internet via a Bluetooth-connected phone, these sources are used in the following order of priority. Firstly, connection via Wi-Fi networks is used; secondly, via a Bluetooth-connected phone; and thirdly, via the car's built-in modem.
