Abstract: An integral navigation and A/V system for preventing an audio signal from being interrupted due to a voice guidance of a navigation system, and a control method thereof are provided. The system includes: a navigation module having geographical information, and measuring a self position, mapping the measured self position to the geographical information, setting a path to an inputted destination, mapping the set path to the geographical information, and outputting a position based guidance voice; an audio processor for receiving and distributing the audio signal to corresponding channels, outputting the distributed audio signal, and receiving and outputting the guidance voice to the speaker corresponding to the channel; and a controller for controlling the audio processor to distribute the audio signal and the guidance voice by channels.

Abstract: An apparatus and method for automatically converting a broadcast channel using a global positioning system is provided. The apparatus includes a storage unit for storing a lookup table; a global positioning system module for receiving position signals, and determining a current position; a receiver for receiving a broadcast signal; a first broadcast channel selector for selecting only a first broadcast signal of a desired broadcast channel; a second broadcast channel selector for selecting only a second broadcast signal of a change-expected broadcast channel; and a controller for receiving the position information, determining a current broadcast area, receiving signal-to-noise ratios of the first and second broadcast signals, and controlling the first and second broadcast channel selectors to select a broadcast signal having a good signal-to-noise ratio.
