Abstract: Scan a plurality of broadcast signals, select and receive one of the scanned broadcast signals and determine parameters about the received broadcast signal. Assign a priority to the received broadcast signal based on the parameters, and store the parameters and priority in memory. Redetermine the parameters in priority order in a manner that reduces the time for redetermining. Reassign a priority to the received broadcast signal based on the redetermined parameters, and update in memory the redetermined parameters and priority.

Abstract: A method for receiving broadcast signals includes selecting a broadcast signal, and receiving selected broadcast signal. Determine parameters about the selected broadcast signal wherein the parameters are based on supplemental broadcast data. Choose a scan interval based on the parameters.

Abstract: A method of selecting an audio source includes the step of providing an audio system that includes a source of audio data which can be supplied to a speaker to produce sound. A portable audio source device is enabled to be operatively connected to the audio system. When the portable audio source device is operatively connected to the audio system, the audio system automatically stops supplying audio data from the source of audio data to the speaker and starts supplying audio data from the portable audio source device to the speaker to produce sound.

Abstract: Vehicle data generated by circuitry of a vehicle is received and functions of a personal navigation device, which are otherwise used to process device navigational data that are generated by navigational circuitry in the personal navigation device, are used to process the vehicle data to produce output navigational information. User interlace commands and navigational data are communicated between a personal navigation device and a media head unit of a vehicle, the user interface commands and navigational data being associated with a device user interface of the device, and a vehicle navigation user interface at the media head unit displays navigational information and receives user input for control the display of the navigational information on the media head unit, the vehicle navigation user interface being coordinated with the user interface commands and navigational data associated with the device user interface.
