USING THE MULTIMEDIA SYSTEM AS A WI-FI HOTSPOT

Requirements:

The device to be connected supports at least one of the types of con‐

nection described.

The connection types shown depend on the device to be connected.

The function must be supported by the multimedia system and by the

device to be connected. The type of connection must be selected on the

can purchase an Entertainment Package via the Mercedes-Benz

Store. In order to use the data package included, you must con‐

clude your own contract with a mobile phone network provider

via the Mercedes-Benz App. This can be terminated at any time

and incurs no costs. Without this contract it is not possible to

use the services included in the previously acquired Entertain‐

ment Package. The availability of this option is dependent on the

country.

If the data package option is not available or can be upgraded,

you can purchase data volume directly from the mobile phone

network provider for a fee. The availability of this option is

dependent on the country.

Some functions may first need to be activated on the device

being connected. More detailed information can be found in the
