Abstract: A method of providing connectivity navigation with a head unit in a navigation system includes the steps of determining a reception state of global positioning system (GPS) information, searching for at least one device connected by wire or wirelessly, receiving position sensor information from the searched devices, determining reliability of the position sensor information, and selecting information of a device having high reliability as received information based on the determined reliability. In addition, a navigation system including the head unit, a vehicle controller, a mobile terminal, and a telematics server performs the method of providing connectivity navigation.

Abstract: A method for limiting linkage between devices may limit linkage between items that do not coincide with each other among items of service identifiers of a first device and a second device by comparing the service identifier of the first device and the service identifier of applications of the second device to each other is provided. The method includes receiving, by a second device, a service identifier transmitted by a first device, comparing, by the second device, the service identifier received from the first device to a service identifier of the second device and requesting, by the second device, to the first device to transmit information determined to be the same item. The method also includes receiving, by the second device, the requested information from the first device, including the item allowing the information provision.

Abstract: Flow of data is controlled in a mirror link system in which an AVN system included in a vehicle is interlinked with a wireless terminal. It is determined whether the vehicle is driven or not. Upon determining that the vehicle is not being driven (e.g., the vehicle is parked), the AVN system is interlinked with the wireless terminal through a first streaming protocol and a first control protocol. In contrast, upon determining that the vehicle is being driven, the AVN system is interlinked with the wireless terminal through a second streaming protocol and a second control protocol different from the first streaming protocol and the first control protocol. The first streaming protocol transmits video images and sounds associated with a video from the wireless terminal to the AVN system, while the second streaming protocol transmits only the sounds associated with a video from the wireless terminal to the AVN system.
