Our take on the Rockford Fosgate RFBTAUX

This is Bluetooth interactivity made so simple. Just plug Rockford Fosgate's Bluetooth adapter into your car's cigarette lighter, plug its cable into the AUX input on your car stereo, and pair up your phone. Boom, you've got streaming audio in your car. Now that you've got your music library, Pandora, Spotify, Rhapsody and other music apps at your total disposal, you might wonder how you ever lived without this little gizmo.

Easy listening


The Rockford Fosgate RFBTAUX's USB port also converts your cigarette lighter into a charging station.

Rockford Fosgate also includes a convenient USB port on the adapter, so you can charge your phone or tablet on the road.

So far it does what it is suppose to do.

Allowed me to finally play music from cell phone via bluetooth

APowers from Southbridge, MA on 7/12/2016

Crutchfield Customer Review (What's this?)

However playing music via bluetooth on the Equinox LS was so cumbersome that I traded in my new vehicle for a RAV4. Hard to believe Chevrolet sold a model with only AM, FM and Sirius FM (no bluetooth).



HK Bluetooth with power from cig lighter

cc8411 from Sikeston, MO on 6/22/2016

Crutchfield Customer Review (What's this?)

Easy as pie to hook up. Plugs in the aux input and a power plug for cig lighter in glove box, funky design by MB on this, but it works great. It could not be any better. I love it. Very little sound reduction to the music. I like it. Took like 30 seconds to set up.

Pros: Easy, cheap, works great, remembers up to 5 phones or whatever has bluetooth

Cons: a little background noise but it is an aux cord

Wonderful Bluetooth Product

Alan from Roanoke, VA on 6/16/2016

Crutchfield Customer Review (What's this?)

This product works great Easy to install & easy to pair Also it remembers once paired Cannot answer calls but was not looking for that Wanted easy way to wireless via Bluetooth connect phone or pad to truck stereo This product does that easily and sound quality is good too. And if phone rings it allows call to be answered using other Bluetooth device Highly recommend-would definitely buy it again.

Pros: Easy to install Easy to pair Good sound Simple to operate Met all my needs & expectations

Cons: None

Josh from Denver, CO on 5/20/2016

Crutchfield Customer Review (What's this?)

Love the feature of this product that turns itself on and off when car is turned on and off. Most Bluetooth devices that allow AUX ports to be Bluetooth compatible must be powered on and off manually.

Pros: Auto On/Off


Great Device

John S. from Woodbury, NJ on 5/13/2016

Crutchfield Customer Review (What's this?)

Easy install and great way to get Bluetooth in your car to stream!

Pros: Price and Quality

Cons: None for me at all

Rockford Fosgate RFBTAUX

Jose from Nogales, AZ on 4/25/2016

Crutchfield Customer Review (What's this?)

Since my BMW does not come with a Bluetooth feature, I wanted a simple device that would allow me to play Pandora stations from iPhone without the burden of having it connected to a wire. This little device is very practical and simple to synchronize with my phone. I am very happy with my purchase

Pros: Practical, easy to connect, reliable

Cons: I noticed a slight deterioration on sound quality. But this is probably just natural on all Bluetooth devices and not particular to this device.

Brilliant car stereo upgrade for older cars

Swami from Blacklick, OH on 1/31/2016

Crutchfield Customer Review (What's this?)

The Rockford Fosgate blue tooth adapter provides the functionality of bluetooth and USB port for older cars that don't have these built in. This adapter allows you to untether your phone and stream audio via bluetooth through your car stereo. Setup entails plugging device into cigarette lighter socket and connecting it with the provided cable into the auxiliary port. A USB port in the device provides an outlet to charge your phone in place of having a dedicated phone charger. After trying this product in one vehicle, I was so pleased that I purchased a another one for our second car.

Pros: Well designed. Easy installation and setup. USB port replaces car charger.

Cons: None.

Blue Tooth for Old School Rides!

SteveW from Kentucky on 9/17/2015

Crutchfield Customer Review (What's this?)

This is a clever device. I was originally looking at blue tooth add-ons that featured hands-free calling, but what I really wanted was the ability to stream music from my phone. This unit does that quite well. It connects easily to my phone and initial set-up took only minutes. The unit also has a port to charge my phone, which I really needed. Downfall? Lots of alternator noise picked up. If the music's loud, the alternator whine is hardly noticeable. Otherwise, be prepared to deal with the noisy whine.

Pros: Easy to use, reasonably priced.

Cons: Coil-y cord that connects between the RFBTAUX and your head unit is ugly and short. Alternator noise can be heard.


JoeB from Louisville,Ky on 8/31/2015

Crutchfield Customer Review (What's this?)

Pros: Connects easily

Cons: None

Easy Bluetooth

Midnightclubber from Indiana on 5/24/2015

Crutchfield Customer Review (What's this?)

I had a device that needed to be charged, after about ten charges the mini USB failed. This device plugs into power no charging. push one button and paired easily. I love it, no worries connects instantly every time.

Pros: ease of use. connects easily every time.stays connected.

Cons: Not one that I've found.

Perfect Solution

Mike R from Colorado on 1/31/2015

Crutchfield Customer Review (What's this?)

After driving a rental with bluetooth music streaming I started looking for options to upgrade the factory stereo in my LR3. After passing on several very expensive options I found this Rockford Fosgate bluetooth adapter. For less than $50 I thought I would give it a try. Turns out to be the best money I've spent. The adapter works perfectly, and the sound is much better than using an aux cord. I couldn't be happier.

Pros: Super easy to set up and use. Connects automatically every time I get in the car.

Cons: None.

Great BUT

Pros: Great price and sound

Cons: No phone calls go though


SS87 from the Washington, DC Area on 1/7/2015

Crutchfield Customer Review (What's this?)

This was the perfect device because my regular option 2008 vehicle did not come with Bluetooth. So this was a great addition to my car, especially for long trips. It was also great to help other passengers with their music preferences.

Pros: Very simple, compact

Cons: None found yet

Crutchfield Customer Review (What's this?)

I bought a Toyota Prius without the bluetooth option. This gizmo was made for me. Works perfectly.

Pros: Comes with own power supply so doesn't need charging.

Cons: Couldn't think of any

Simple to us and simlply Awsome

Dale K from Ofallon MO on 9/30/2014

Crutchfield Customer Review (What's this?)

This is a great solution for streaming bluetooth audio thorugh an auxillry jack in your car. The fact that this unit combines the power source and audio connection into a single unit saves unnecasry wiires.

Pros: auto connection to smartphone and single uniti for power and audio connection. simple to use!

Cons: Nothing identified after a month of troublle free use.

Fits my application perfectly

Jim D. from SE Michigan on 5/26/2014

Crutchfield Customer Review (What's this?)

I bought this device to replace a damaged HTC 2200 Bluetooth adapter and the Rockford Fosgate RFBTAUX is much better. I like to listen to podcasts I download to my Samsung S4 while driving and this product is perfect. The HTC sticks out from the aux input jack on the radio with is why it was how it was damaged, I had to remember to turn it off when exiting the car, and it was only usable on battery because it has a buzzing sound when plugged into the charger. The Rockford Fosgate RFBTAUX is powered directly off the car battery thus it turns off when the car is shut off. Since it runs off the car power I can use for extended driving, the HTC would die after a few hours. No trouble paring and it has always connected automatically every time I entered the car. No complaints with the audio quality. Audio cable is just the right length for my vehicle.

Pros: Plug in in, pair it and forget it.

Cons: None

Works good

Anonymous from Central Wisconsin on 5/20/2014

Crutchfield Customer Review (What's this?)

Once your Bluetooth device connects to it, it works great. On iphone5 I have to go into Settings>Bluetooth>find the "RFBTAUX" device, then go to the little information bubble, forget this device, then it says "RFBTAUX not paired", tap on it to pair & it will connect. This has to be done every time the car is turned off & then back on to reconnect. It would be nice if it would auto connect like my vehicles hands free does, but that's my only con

Pros: Works great once connected Has USB port to charge device

Cons: Doesn't auto connect to Bluetooth, has to be reconnected every time the car gets shut off.
