The invention discloses an unshielded vehicle-mounted terminal, which comprises an information acquisition module, a data transmission module, a control module and a positioning module, wherein the control module controls the data transmission module, the positioning module and the information acquisition module to work; the information acquisition module is used for acquiring information in the vehicle, around the vehicle and of the vehicle; the data transmission module is used for being connected with other terminals and transmitting data; and the positioning module is used for positioning the vehicle. The unshielded vehicle-mounted terminal is different from the traditional vehicle-mounted terminal equipment in the hardware architecture and product structure, a video display module is not adopted, related video display processing is not required to be performed, a low-specification central processing unit (CPU) processor can be adopted, and the functions such as unshielded navigation, audio and video play, traveling image video recording, vehicle state acquisition, remote control, remote monitoring, hands-free calls and real-time back-up image of the vehicle-mounted terminal are realized at low cost.
