WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

With the video connection function for the smartphone it is possible to play video files (films, TV programs, podcasts, etc.) saved on the smartphone on the central information display (CID) in the vehicle. The image display is only available when the vehicle is stationary for safety reasons. The image data is transmitted analogously via the CVBS line (Color Video Blanking Signal) to the headunit.

As soon as the smartphone is connected with the vehicle, it appears as an external device in the CD/Multimedia menu on the CID. The videos available on the smartphone can be selected via the controller/MINI joystick. By selecting a video the smartphone is requested by the headunit to play via the USB. The smartphone issues the image data to the CVBS line via its video output. The headunit receives this image data and processes it accordingly so it can be displayed on the CID.
