ON-VEHICLE DEVICE, INFORMATION OUTPUT METHOD, AND INFORMATION PROVIDING SYSTEM

摘要

A on-vehicle device (10) which receives and outputs a radio wave containing at least direction information as information includes: detection means which detects a radio wave; and control means which compares the detection direction received from the direction detection means which detects the direction of the vehicle head to the direction information so as to judge whether the information can be outputted. Thus, it is possible to provide an on-vehicle radio device which can provide only the information required by a user, a method for outputting the information, and an information providing system.
