The following controls can be used for operation of the function:

The "ON" button is read in internally by the COMAND controller unit. The COMAND controller unit receives the signals from the Audio/COMAND control panel over the telematics CAN.

The right multifunction steering wheel button group sends its signals via the following route:

Steering wheel electronics →

Steering LIN →

Steering column tube module control unit →

Chassis CAN 1 →

Electronic ignition lock control unit →

Chassis CAN 2 →

Instrument cluster →

Interior CAN →

COMAND control unit

The Internet connection function is divided into the following subfunctions:

Additional function requirements for Internet access (dial-up) on vehicles with code ZU8 (USA national version) 

Internet access (dial-up) on vehicles with code ZU8 (USA national version) 

The function is activated by calling up the menu, e.g. via the application bar on the Audio/COMAND display. The selection is confirmed e.g. by pressing the Audio/COMAND controller on the Audio/COMAND control panel.

The signals from the Audio/COMAND control panel are received by the COMAND controller unit via the telematics CAN, processed and shown on the Audio/COMAND display via an LVDS line.

The Mercedes-Benz Internet and Application Gateway is generally used as the server for the connection to the Internet. Through the encrypted connection to the Mercedes-Benz Internet and Application Gateway, the user is only generally identifiable as a user of the Mercedes-Benz Internet and Application Gateway when surfing and using services and cannot be located in the network via his/her activities.

IMPORTANT If the COMAND controller unit is used as a hotspot or if the IP-Radio service is activated, the data traffic is not processed via the Mercedes-Benz Internet and Application Gateway.

The COMAND controller unit sends data to the mobile telephone network via the following route:

Wi-fi antenna →

HERMES control unit →

Emergency call system antenna 1 and emergency call system antenna 2

IMPORTANT The HERMES control unit uses emergency call system antenna 1 and emergency call system antenna 2 to send and receive at the same time, i. e. both antennas constitute transmission and reception diversity.

In accordance with requests from the COMAND controller unit, the Mercedes-Benz Internet and Application Gateway exchanges information with the World Wide Web and the service providers via the Internet and transmits the received data to the COMAND controller unit in the opposite direction.

IMPORTANT Activating a manual or automatic emergency call, breakdown assistance or an MB information call interrupts the Internet connection.

Additional function requirements for Internet access (dial-up) on vehicles except code ZU8 (USA national version) 

Internet access (dial-up) on vehicles except code ZU8 (USA national version) 

The function is activated by calling up the menu, e.g. via the application bar on the Audio/COMAND display.

With a connection via Personal Area Network (PAN), the Internet enable function must be activated on the mobile phone.

With a connection via Dial-up Networking (DUN), the dial-up data must be provided via the COMAND controller unit. By turning the Audio/COMAND controller, the "System" panel is shown in the foreground on the Audio/COMAND display. After selection or addition of the mobile telephone network provider, further access information (e.g. on the tariff) must be specified that can be obtained from the mobile telephone network provider. As soon as the data is available, the connection to the Internet is set up.

The signals from the Audio/COMAND control panel are received by the COMAND controller unit via the telematics CAN, processed and shown on the Audio/COMAND display via an LVDS line.

IMPORTANT Fees: Internet access and services are free from Mercedes-Benz. However, fees must be paid to the mobile telephone network provider in accordance with the respective mobile phone contract. Display options and the "Scissors" (disconnect connection) soft key in the function bar make it easier to manage costs with either a time or data volume contract.

The Mercedes-Benz Internet and Application Gateway is generally used as the server for the connection to the Internet. Through the encrypted connection to the Mercedes-Benz Internet and Application Gateway, the user is only generally identifiable as a user of the Mercedes-Benz Internet and Application Gateway when surfing and using services and cannot be located in the network via his/her activities.

IMPORTANT The data traffic of the IP-Radio service is not processed via the Mercedes-Benz Internet and Application Gateway.

In vehicles except code EP3 (Universal Telephony package) and except code EG1 (Auto telephony) and with basic telephony, the COMAND controller unit transmits the signals via the Bluetooth® antenna to the mobile phone, which establishes a connection with the mobile telephone network.

In vehicles with code EP3 (Universal Telephony package), the COMAND controller unit transmits the signals to the mobile telephone network via the following route when comfort telephony is used:

Bluetooth® antenna →

Mobile phone →

Universal smartphone cradle →

Mobile phone contact plate →

Cellular telephone system antenna amplifier/compensator →

Multifunction antenna

In vehicles with code EG1 (Auto telephony), the data can be transmitted via two different routes from the COMAND controller unit to the telephone module with Bluetooth® (SAP). We recommend connecting the telephone module with Bluetooth® (SAP) via the integrated USB interface (Universal Serial Bus) and the connecting cable to the multimedia connection unit, as a higher data rate is hereby achieved. The data is transferred here by the COMAND controller unit via the following route:

Multimedia connection unit (USB port 1 or USB port 2) →

Connecting cable →

Telephone module with Bluetooth® (SAP profile)

If the telephone module with Bluetooth® (SAP) is not connected to the multimedia connection unit, it receives the data from the COMAND controller unit via the Bluetooth® antenna. The application quality is restricted by the low data rate when connected by Bluetooth®.

The telephone module with Bluetooth® (SAP profile) sends the data via the following route to the mobile telephone network via an encrypted connection:

Mobile phone contact plate →

Cellular telephone system antenna amplifier/compensator →

Telephone and stationary heater antenna changeover switch or Mobile phone and stationary heater radio remote control antenna splitter →

Multifunction antenna

In accordance with requests from the COMAND controller unit, the Mercedes-Benz Internet and Application Gateway exchanges information with the World Wide Web and the service providers via the Internet and transmits the received data to the COMAND controller unit in the opposite direction.

IMPORTANT Multiple use of mobile phone: Basically, several functions can be processed at the same time via mobile phones that are suitable for the Internet connection function, i. e. it is possible to make phone calls while connected to the Internet. However, this depends on the quality of the respective network. If the network connection is too weak, the Internet connection is merely maintained while the telephone call is being made.

Internet usage 

The Internet can be used in the vehicle in the following ways:

The services of the Mercedes-Benz Internet and Application Gateway are supplementary to the navigation system and can be used while driving. Free surfing is only possible if the vehicle is stationary. The COMAND controller unit receives the vehicle speed signal via the interior CAN from the instrument cluster.

Audio signals from the Internet can also be played back. The COMAND controller unit outputs the audio signals from the Internet via the speaker system or, on vehicles with code EU9 (Harman Kardon® Logic 7® surround sound system), transmits them via MOST to the sound system amplifier control unit.

IMPORTANT If no control signals for the Internet function are received for a certain time, the COMAND controller unit automatically disconnects the Internet connection. If necessary the Internet connection is automatically set up again.

IMPORTANT Model 463

as of model year 2017 up to model year 2019

with code EU4 (COMAND Online)

except code ZU8 (National version for USA)

The time period for automatic disconnection can be defined on the "System" panel.

Use of Mercedes-Benz Internet and Application Gateway services 

By turning the Audio/COMAND controller, the panel for the services is shown in the foreground on the Audio/COMAND display. The selection is confirmed by pressing the Audio/COMAND controller on the Audio/COMAND control panel.

The individual services and the options for the services can now be actuated in the same way using the Audio/COMAND control panel. The method of operation and the screen displays have been adapted to the general operation of the COMAND controller unit and the design of the displays on the audio/COMAND display to such an extent that operation is essentially intuitive.

The signals from the Audio/COMAND control panel are received by the COMAND controller unit via the telematics CAN, processed and shown on the Audio/COMAND display via an LVDS line.

The following services can be used via the Mercedes-Benz Internet and Application Gateway (examples):

IMPORTANT Other services are available or can be retrofitted, but they are not described here in further detail.

Search for points of interest 

Search terms can be selected from lists or entered on the character bar on the audio/COMAND display. Points of interest can be searched for a search term, e.g. at the current location, at the navigation destination or at an arbitrary location (free entry).

IMPORTANT The area that is being searched is defined under "Options".

The search results appear in the form of a list. If the list entry contains a telephone number, a telephone connection can be set up.

Search results can be stored in the address book or under "Personal points of interest" on a Secure Digital (SD) card in the SD card slot of the COMAND controller unit.

A selected search result can be transferred to the navigation system, and in this case the COMAND controller unit switches to the navigation menu.

Weather 

Weather information is displayed either as a weather data table or as a weather map.

In the basic setting the current weather data for the current location of the vehicle and forecasts for the next few hours are displayed.

However, different time periods and locations can be selected, such as information about the weather along the route or at the destination. In addition, city names or ZIP codes can be entered with the character bar on the audio/COMAND display. The most up-to-date measurements and forecasts are always displayed.

The topicality of the data depends on the relationship between the time of the query and the time of the last measurement.

IMPORTANT Weather data is sent from the weather station nearest to the entered location. It can take a while to transfer and display the respective data, particularly if maps are being displayed or with a weak network connection.

Additional function requirements for loading points of interest or routes (with code ZU8 (USA national version)) 

IMPORTANT Special destinations or routes that have been sent to the vehicle over the Internet (e.g. via Google Maps) are also sent to the vehicle by way of the Service Center.

Load points of interest or routes (with code ZU8 (USA national version)) 

The Service Center transmits POIs or routes via the mobile telephone network, the emergency call system antenna and the multifunction antenna to the HERMES control unit. If circuit 15 is OFF, the HERMES control unit stores the data in an integrated buffer.

IMPORTANT If the capacity of the buffer is exceeded, the oldest POIs or routes are overwritten.

If circuit 15 is ON, the HERMES control unit sends the points of interest or routes over the following route as soon as the COMAND controller unit is switched on:

Diagnostic CAN →

Electronic ignition lock control unit →

Interior CAN →

COMAND control unit

The reception of information is displayed by the COMAND controller unit by means of a pop-up window on the audio/COMAND display.

Using the context menu, the points of interest or routes are copied from the buffer to the navigation system or the address book of the COMAND controller unit. Only then are the POIs and routes transmitted to the vehicle permanently available in the vehicle.

IMPORTANT Data for navigation can be sent by the Service Center as part of an emergency call, breakdown assistance or an MB Info call.

IMPORTANT Due to the limited capacity of the buffer, transmitted POIs/routes are available for downloading only for a limited period of time (approx. 7 days), and only a limited number of POIs/routes can be made available for download within the same time period.

IMPORTANT If the point of interest or route is only needed immediately and not permanently, the navigation can be started directly without the point of interest or route being stored permanently. This function is also available without an SD card.

Additional function requirements for loading points of interest or routes (except code ZU8 (USA national version)) 

IMPORTANT Points of interest that have been found on the Internet via Google Maps or routes that have been planned using Google Maps can be transmitted via Google Maps to the vehicle.

Load points of interest or routes (except code ZU8 (USA national version)) 

The "Load points of interest or routes" service lists the points of interest and routes that have been sent to the vehicle and makes it possible to transfer them from the buffer to the navigation system or the address book of the COMAND controller unit using the context menu. Points of interest and routes that have been sent via Google Maps are then only continuously available in the vehicle if they have been transferred to the navigation system or the address book of the COMAND controller unit using the "Load points of interest or routes" service.

IMPORTANT If the point of interest or route is only needed immediately and not permanently, the navigation can be started directly without the point of interest or route being stored permanently. This function is also available without an SD card.

IMPORTANT If more POIs and routes are sent than can be stored in the clipboard, the oldest POIs and routes are overwritten.

IMPORTANT Due to the limited capacity of the buffer, transmitted POIs/routes are available for downloading only for a limited period of time (approx. 7 days), and only a limited number of POIs/routes can be made available for download within the same time period.

IMPORTANT Model 463

as of model year 2017 up to model year 2019

with code EU4 (COMAND Online)

with code ZJ1 (Version for Japan)

Points of interests can be loaded but no routes. The POIs must always be taken from the COMAND controller unit address book and selected from there as the navigation destination.

Additional function requirements for free surfing 

Unrestricted surfing 

In order to connect to the Internet, either a URL must be entered or a page that is stored under "Favorites" must be selected.

In order to navigate on the page, you can either move the cursor using the Audio/COMAND controller of the Audio/COMAND control panel as though you were using a mouse, or jump from one selectable object (e.g. link) to the next on the current page by turning the Audio/COMAND controller (this highlights the object). A marked link is opened by pressing the Audio/COMAND controller of the Audio/COMAND control panel vertically downwards. The "back" button opens the context menu. When jumping to a text entry field, the character toolbar on the audio/COMAND display can be used to enter text.

The browser can work with HTML5. Downloading is not possible when surfing with the mobile browser.
