What is the FM frequency for car Bluetooth?
2 Answers
When using a car MP3 player, simply tune the radio to the same frequency as the MP3 player. Here are some related details about car Bluetooth functions: 1. Enables Bluetooth calling: It allows hands-free phone calls by connecting to your mobile via Bluetooth while driving, keeping both hands free and reducing traffic accident risks. 2. Automatic mobile phone recognition: No cables or phone holders are needed to connect your phone; drivers can control their phones without touching them, even keeping both hands on the steering wheel, using voice commands to answer or make calls. Users can conduct calls through the car's audio system. 3. Enjoy music outdoors: During holidays or road trips with friends, take out the car Bluetooth hands-free device, connect it to your phone, and enjoy your favorite music.
I've been in car modification for several years and often encounter people asking about Bluetooth FM frequencies, which is actually a misunderstanding. Bluetooth itself is a wireless technology that operates on the 2.4GHz band, not FM radio frequencies. However, many people use those FM transmitters that plug into the cigarette lighter—they convert your phone's Bluetooth audio into an FM signal and broadcast it for your car radio to pick up. The frequency range is usually between 87.5MHz and 108MHz, and the key is to choose an unused frequency to avoid interference and choppy music. I used to recommend edge channels like 88.1 or 92.7—just scan with a phone app to find an open one. Setup is simple: first pair the transmitter with your Bluetooth device, set the frequency, then tune your car radio to the same one. If the connection is stable, it's quite convenient for daily commutes, more hassle-free than an aux cable. Just remember to check the transmitter's plug to ensure it's not loose, as that can affect performance.
