VNC Automotive is designed for OEM Partners to provide seamless integration of VNC remote access technology within their own products. A VNC Server installed on a mobile device can be viewed and controlled remotely by a VNC Viewer embedded into a new or existing Human Machine Interface (HMI) running on the vehicle head unit or aftermarket infotainment solution. For more information see the Product Brochure (PDF) and the Automotive Datasheet (PDF).

Packaged as a Software Development Kit (SDK), the VNC Viewer SDK provides support for the following mobile connectivity protocols:

VNC Automotive
Based on the very latest version RFB4 protocol.
RealVNC is a core member of the Car Connectivity Consortium supporting the MirrorLink™ specification, which uses VNC* technology.
* Built on the older RFB3.8 protocol
iPod Out
iPod Out is Apple's connectivity feature released in iOS 4 that allows a connected iPhone 3GS, iPhone 4 or iPod touch to output and display the iPod video interface on the head unit screen and to accept remote control commands from vehicle input devices.

One advantage of VNC Automotive is it provides OEMs with the ability to have a single common HMI solution with access to the widest coverage of mobile devices, including many existing legacy devices already in use with end users.

Users are able to access their mobile content, such as navigation applications, traffic updates, music libraries and internet radio stations from the vehicle’s main display unit. The mobile device can be directly accessed and controlled from the vehicle’s head unit touch screen, bezel keys, steering wheel switches and by voice command, ensuring content can be access safely and simply.

VNC Automotive supports a number of different formats and solutions which are detailed below. It is already being deployed by blue-chip partners and automotive OEMs with defined in-vehicle production dates. These include:

  • Clarion
  • Elektrobit
  • QNX
  • Wipro
  • Visteon
  • Cybercom
  • Teleca
  • Softwire
  • Panasonic
  • ST
  • TI
  • Freescale

Security and Connectivity

VNC Automotive uses the very latest RFB4 protocol and provides backward compatibility for RFB3 variants, including MirrorLink™. The solution also gives OEM customers access to industry standard authentication and encryption options to provide a highly secure connection.


RFB4 also has message extension options that allow exchange of messages between the head unit and mobile device. This mechanism can be used for numerous purposes; one significant use is to report device application capabilities so that the head unit can police display and control of inappropriate applications by interlocking access and use with vehicle speed. Thus the important issues of driver distraction and a consistent quality of user experience can be controlled by the automotive OEM, meeting both brand quality constraints and legal and regulatory compliance needs.

VNC Automotive is compatible with virtually any mobile device and embedded automotive head unit platform.
