The system features comprehensive equipment, including a 14.7 centimetre colour display, USB connection in the glove compartment, CD player and telephone keypad. Via Bluetooth® it is now possible to display SMS and stream music from an external device to the radio. The classic hands-free operation is naturally obligatory.

With the Becker® MAP PILOT you can upgrade the standard-fit Audio 20 CD radio to a complete navigation system. The control unit can be simply and securely inserted and locked into the pre-installed holder in the glove compartment.When you need to update it, the control unit can be easily removed again at any time and connected to your computer.

This includes:

An additional aerial is used for digital radio (DAB).This provides reception at near CD quality, a broader selection of stations, as well as more detailed programme and traffic information. Switching between analogue and digital reception is automatic according to network coverage and signal strength.

The Harman Kardon® Logic 7® surround sound system with Dolby Digital 5.1/DTS, a 450-watt multi-channel DSP amplifier and twelve high-performance speakers including a subwoofer delivers outstanding sound characteristics. The speed-sensitive volume control continually adjusts the volume to the vehicle speed to guarantee a consistent sound impression at all times.

Optimum reception and transmission, high standard of operating reliability, convenient use of telephone functions and possibility to use several mobile phones in one vehicle: all this and a lot more is provided by the Convenience Telephony option.

All that's needed is the Mercedes-Benz head unit with screen, a compatible mobile phone and a cradle to connect the phone to the exterior aerial via a fixed interface in the centre console. In conjunction with the optional COMAND Online, the system features the LINGUATRONIC voice control system with which the driver can operate almost all the telephone, radio and navigation functions by voice command.

The integrated Bluetooth® interface allows wireless interaction with a compatible mobile phone. You can also use the charging function to charge your mobile phone. The functions of your mobile phone can be accessed via the multifunction display – incoming text messages can also be displayed here. And if you want to make a call, you can select your contact safely and intuitively using the control unit.

The optimised Media Interface, including the consumer cable kit, provides a solution for connecting portable media players in the centre console which cannot be connected via the standard USB mass storage device. This includes the iPod® and iPhone® as well as media players with Media Transfer Protocol (MTP), for example, from Creative, Philips, Sandisk, Samsung or Sony. The system makes it easy to read additional information such as track title, album, artist etc. (where available) on the vehicle's main display.

Once the portable media player has been connected, the following functions are available:

The COMAND Online multimedia system is the highlight of the new telematics generation. This innovative system features an internet browser and combines all audio, telephone and navigation functions.

Components of the COMAND Online multimedia system:

The digital ViaMichelin travel guide, which includes the ViaMichelin restaurant guide, is an optional extra with the COMAND Online multimedia system and is available in five languages covering 36 European countries. It gives extensive information on restaurants, hotels, points of interest and tourist routes.

The search function makes it easy and quick to locate points of interest nearby or at the destination. Grading symbols from the ViaMichelin help the user to select restaurants, hotels, points of interest and tourist routes. The software also provides other multimedia information (audio files, images and texts) on the ViaMichelin POIs. The travel guide contents can be updated free of charge via the Mercedes-Benz portal.

A screen on which two different types of content are displayed simultaneously: While the driver checks the navigation instructions, the front passenger can enjoy a film without interruption on the same display. Perfect entertainment that you can see and hear at a high technical level and in excellent sound and picture quality.

To ensure the driver is not distracted by the entertainment programme, the front passenger can use headphones to enjoy the selected programme. And of course the front passenger can continue to access the telephone and navigation functions as all the information for the COMAND Online multimedia system can still be called up on the display.

The telephone module with Bluetooth® (SAP profile) is an enhancement to convenience telephony. It enables a mobile phone to be connected through the Bluetooth® SAP profile (SIM access profile) or for it to be directly operated by inserting the SIM card in the built-in SIM card reader.

The functions at a glance:

The TV receiver enables television viewing during driving breaks: The receiver unit processes the digital signals in DVB-T standard and is controlled using the COMAND Online multimedia system, whose display is positioned in the driver’s central field of vision and also shows the image.

Sound output is via the vehicle's speaker system. The receiving aerial is integrated in the rear window. At speeds above approx. 6 km/h, the image is switched off for safety reasons and reappears when the speed falls below this limit.
