Considering the deficiency of the presently autonomous vehicle navigation terminal on dynamic updating of map data and reception of real-time traffic information, this paper presents the design options, which is based on the thought of combining the network with the autonomous navigation. It is accomplished by the combo vehicle navigation terminal which is based on GPRS. This paper introduces the structure and principle of S3C44B0X, GPS, General Packet Radio Service(GPRS), electrical source and other major modules, debugs the terminal and optimized the data received by GPS. The design options of hardware, while combining with software, is conducive to achieve the dynamic updating of map data, and the dynamic navigation which is based on the real-time traffic information.
