Compared with the FM Bluetooth transmitter, the signal transmission through the AUX port is more stable, faster, and the Bluetooth connection is simpler (because the FM Bluetooth transmitter is a mobile phone connected to the transmitter via Bluetooth, and then the transmitter is connected to the car via FM frequency modulation. On the speaker equipment, there are more relays, and FM is easily interfered with by radio waves. And this is the Bluetooth connection from the mobile phone to the receiver, and the receiver is directly connected to the audio equipment through the cable, so the transmission signal is better and the connection is better. simple) 4.
