To be able to connect the car to the Internet via a Bluetooth-connected phone, the phone has to have already been connected to the car via Bluetooth for a first time.
Make sure that your phone supports tethering and that this function is activated. On an iPhone, this function is known as "tethering". On Android phones, this function may have different names but is frequently known as "hotspot". For iPhones, the menu page "tethering" must also be open until the Internet connection has been established.
If the phone has been connected via Bluetooth previously, press Settings in the centre display top view.
Tick the box for Bluetooth Internet connection under the heading Internet connection.
If another connection source has been used, confirm the option to change connection.
Your car is now connected to the Internet via the Bluetooth-connected phone.
The telephone and network provider must support tethering (Internet connection sharing), and the subscription must include data.
When using Apple CarPlay, it is only possible to connect the car to the Internet using Wi-Fi or the car modem*.
