The system connects the smartphone to the car through USB, Bluetooth or Wi-Fi and sync the content between the Headunit and the companion app. For example if the Headunit does not have the latest map update, but this has already been downloaded on the phone then the new content will be uploaded to the car. The same happens with favorite destinations, etc. back and forth.
In addition to that the connection established to the phone can leverage the data plan of the user to download content: local search request, real-time traffic, speedcam warning, etc.
Last but not least the auto maker can use the connectivity to retrieve car data from the vehicle CAN bus in order to perform remote diagnostics readouts or offer additional services to the customer, for example, maintenance appointments.
