"Decoding the Mystery: How Your Car Identifies Radio Songs"

Car radios now display song titles thanks to Radio Data System (RDS) or Radio Broadcast Data System (RBDS) in America, which sends data along with the FM radio signal. RDS transmits station IDs, program types, and song titles, allowing receivers to display this information. HD Radio, a digital and analog broadcasting technology, offers additional channels and data, including images. Gracenote, used in car head units, provides track information for Bluetooth streaming audio.
