In this paper, we newly developed a small-size software radio terminal that can realize global positioning service (GPS) navigation system, vehicle information and communication system (VICS), electronic toll collection system (ETC), AM/FM radio broadcasting services on middle wave (MW) and very high frequency (VHF) bands, FM multiplex broadcasting system, and several modulation schemes such as BPSK, ASK, QPSK, GMSK, and π/4QPSK by downloading software to realize each system from wired and wireless networks. The developed terminal realizes simultaneous multiple services when users would like to use several radio communication services in the driving situation by using our proposed multitask algorithm. The developed terminal has a size of 17.5cm wide, 19.0cm deep, and 5cm high and worked at DC-12.0 V and around 2A. The size and electrical power consumption are quite small and low and acceptable for consumers such as car drivers. In this paper, we introduce the configuration and proposed key technologies in our developed terminal and measure the software configuration time.
