ABSTRACT:
A vehicular navigation and data retrieval system features, on-board, a navigation system (1) and a compact disk (CD) player (2) coupled to said navigation system and adapted to hold, and selectively retrieve data from, at least one audio CD (3) and at least one navigation data CD. A method of retrieving, from disk, navigation data for use by said navigation system (1), features the steps of determining whether said navigation system has an intermediate need for navigation data from said data CD (4), discriminating when said CD player (2) is playing an audio selection from said audio CD (3) and when said player is in a pause adjacent to an audio selection, and directing said CD player (2) to cease playing said audio CD (3) and start retrieving navigation data from said data CD only when said player is in a pause, unless said navigation system has said immediate need and, in the event of such need, interrupting said audio selection to permit navigation data retrieval. This method minimizes disturbing interruptions of the playing of music or other audio selections.
