Better than any short-range FM transmitter, you can get a hardwired Bluetooth FM modulator that plugs directly into the antenna port in the back of the radio head unit, then your stock antenna cable plugs into the modulator. The modulator picks up your Bluetooth and taps the output signal directly into the physical antenna circuit at one of (usually) two selectable frequencies on the radio dial; here's an eBay search for them . There's also similar, older-style FM modulators without Bluetooth, just an aux-in jack; these were commonly used to tap aftermarket CD changers into stock factory radios back in the day. IMO these would be preferable if your audio source (e.g. phone) has an aux-out/line-out or headphone jack. Anywhere you can eliminate a wireless signal in favor of a hardwired connection for audio, the better. Finally, if your stock head unit has a cassette player, there's also rechargeable dummy cassettes with Bluetooth built-in, so your phone would transmit a BT signal to the cassette adapter, which would then feed the audio signal right into the tape head just like playing a real cassette tape.

Can I use a Bluetooth FM transmitter on my boat?
As long as your vehicle has an FM radio connection and an auxiliary port, it can be used to establish a Bluetooth connection. Make sure you turn your transmitter off when not in use, as some vehicles won’t automatically deactivate them.

How do I know which FM frequency to use for my Bluetooth FM transmitter?
You’ll want to match your transmitter’s frequency to that of the desired station on your radio for streaming. Most manufacturers provide a range of available FM frequencies that can be used for pairing. Be sure to choose a clear frequency, as ones in use will not work with a transmitter.

They're all pretty much the same. It's still fm quality. I bought the cheapest on Amazon and it's fine.

FM Bluetooth Transmittor Options/Fits - CorvetteForum - Chevrolet Corvette Forum Discussion
January 9, 2025 - This was on a 99 monte carlo (same radio as c5) No interference and sounded as good as fm gets. Think it was 20 or 30 bucks on amazon. Can't find them now but surely it still exists? edit: LIKE THIS! https://www.ebay.com/itm/274809209816 ... Visit Elektro's homepage! ... Thank you sir! I'll give this one a try and see how it works/fits. It's a lot cheaper than going double din, and keeps the factory/age appropriate head unit. Do you unplug yours every time the car is going to sit? I believe cigarette lighters get power even when the car is off, as someone had previously mentioned.

I live in Africa and drive an older car, I bought a cheap fm transmitter and there is always static or interference. I saw this one on Amazon has good reviews, would spending more reduce or cut the static?
Top answer 1 of 20

Lmao, no. The interference will still be there. Unless you get one that has been set up for more broadcast power. If your car has a cassette player, use one of those cassette to 3.5 mm aux adapters, or if your car has a normal 1 din or 2 din radio slot you should be able to buy and install an aftermarket radio. I know the used ones go for hella cheap over here. Good luck

r/CarAV on Reddit: Need suggestions for Bluetooth FM transmitter that doesn't use cigarette lighter
August 8, 2012 -
I have absolutely no idea if this is the right subreddit, but it was my best guess to where I should start.
My car's cigarette lighter's don't work and it's an issue beyond a mere fuse unfortunatley.
I'd love to be able to listen to my music but all of the fm transmitters that we have require cigarette lighter connection for power. I have a single one that uses an ipod/iphone (pre-lightning) connector that uses the power from the device, but it's no use to me since I have a Galaxy.
Does anyone have any recommendations on bluetooth fm transmitters that would be chargable/run off my phone's charge/not require a cigarrette lighter for power?
Preferably cheaper, but I'd be willing to pay more the more functions it has. (Being able to change songs via the player itself etc.

I think the best option here is to actually fix the cigarette lighter. Almost all of theses have an attached fuse that is worn out over time, called a fusible link. So just buy a new port, they are not hard to install. Two problems fixed at once. What kind of car do you have?

If you don't plan on taking it out of the car, chop the plug in and wire it to any 12v source. (most electronics in the car use 12v)
