Background technology
At present, vehicle mounted multimedia is play navigational system and has been brought new seeing and hearing enjoyment and easily for people's automobile life, existing vehicle mounted multimedia player generally has data input medium such as CD-ROM drive etc., with first development of technology, memory capacity is big, be grown up the gradually standard configuration of many vehicles of the SD card that volume is little, people are provided with SD clamping inlet on panel, and for the vehicle mounted multimedia with navigation feature is play navigational system, the SD card stores the navigation software program for execution, by calling the navigation software executive routine in the SD card, in audio-visual display screen, realize navigation feature during work.
The vehicle mounted multimedia of above-mentioned functions is play its function of navigational system and is fixed when design, decapacitation is carried out outside the update functions of map, can't increase other function, as increase communication function etc., if carry out further function upgrading, unless the vehicle mounted multimedia that more transducer set is new is play navigational system, cost height so not only, also cause unnecessary waste when replacing, along with development of technology, people also can't in time enjoy this progress.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and provide a kind of utilize former vehicle-mounted SD clamping inlet, cost low, simply and easily former vehicle mounted multimedia is play the method that navigational system is carried out function upgrading.
Another object of the present invention also is to provide a kind of said method that utilizes to realize former vehicle mounted multimedia is play the SD upgrade function card device that navigational system is carried out function upgrading.
The present invention achieves the above object by following technical solution:
The method of utilizing vehicle mounted multimedia to play the incidental SD card of navigational system upgrade-system function of the present invention is by a upgrade function card that is complementary with the SD card is set, interlude and miniSD card are set in the upgrade function card, Navigator and corresponding function upgrading module executive routine are stored in this miniSD card, making former vehicle mounted multimedia play navigational system can not only utilize the SD card to call the navigation executive routine of miniSD card in the upgrade function card by interlude, and can realize the operation of function upgrading module corresponding program, thereby realize that vehicle mounted multimedia plays the function upgrading of navigational system.
SD upgrade function card device of the present invention comprise one with the identical joint of former SD card, it is characterized in that, also be provided with single-chip microcomputer in the described SD upgrade function card device, be solidified with in the single-chip microcomputer and can carry out interlude, also be provided with the miniSD card on the SD upgrade function card device, be plugged with the miniSD card on this interface, described miniSD stores Navigator and corresponding function upgrading module executive routine.
Described corresponding function upgrading module executive routine comprises communication module executive routine, antitheft real-time monitoring executive routine.
Adopt the present invention of said method and device to have following beneficial effect:
The present invention has made full use of former vehicle-mounted SD card and has carried out function upgrading, need not to change other formation of former onboard system, can realize the upgrading of function, increase functions such as communication function, antitheft real-time monitoring, updating operation is simple and convenient, cost is low, upgrading module of the present invention also has extendable functions simultaneously, choose corresponding function according to user's needs, as bluetooth communication module function, anti-theft feature, real time monitoring function, abnormal conditions warning function, be that the vehicle mounted multimedia of at present comparatively desirable band SD card is play the navigational system modification scheme.
