Automotive navigation RDS refers to car navigation equipped with a wireless broadcasting system. Below is an introduction to RDS: 1. Definition: RDS stands for Radio Data System, which utilizes subcarriers in FM broadcast signals to digitally transmit information such as station names, program types, program content, and other details. 2. System Features: The RDS system uniquely features an emergency alert function. In case of emergencies, the radio station sends a special signal that forces the radio to broadcast the alert. RDS is highly convenient for use in mobile devices like cars and smartphones. The system employs remote control technology, using a single radio frequency to transmit encoded control signals via subcarriers outside the audio carrier. This eliminates the need to apply for control frequencies, saving frequency resources while enabling control over terminal points.
