Rockford Fosgate

Easy listening

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.

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


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

Fits my application perfectly

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.
Plug in in, pair it and forget it.

Works good

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
Works great once connected Has USB port to charge device
Doesn't auto connect to Bluetooth, has to be reconnected every time the car gets shut off.

3 questions already asked

Does my car need to have an aux input? I have a 2004 Lincoln LS Sport and it doesn't have one. What's my best option to play music from my phone? [ Laurel S  Sep 15, 2014 ]
1 answer
  • I forwarded your question to an Advisor and they responded with the following: If you have the standard 4 speaker radio system in your Lincoln you can add-on a Bluetooth adapter like the Parrot Mki9100 which will then support hands-free calling and wireless audio streaming from a smart phone. The Parrot model does not work on the Lincoln LS models that have navigation or the premium 12 speaker system. At that point you would be looking at a radio replacement to gain the extra features to play music from your phone. I would highly recommend calling in to us and we can go over all the options with you. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Staff  Sep 16, 2014 ]
Does the device connect automatically? [ RIza23  Aug 05, 2014 ]

  • You push the button/light on the plug in and it begins flashing. Once it begins flashing it will show up on your iphone bluetooth devices list. Then you just click on it to connect. [ Michael   Aug 07, 2014 ]
  • After you plug it into power it should show on your bluetooth device as RFBTAUX. The device has a blue light above the USB and you can push it to "pair" with your device. I've used it on a boat for 2 weeks and it does what it should. Handy. [ Christopher   Aug 06, 2014 ]
  • If you have it plugged into a always powered outlet then yes, if the power goes off when the ignition is turned off, then you will have to push the blue button to connect. [ Barry   Aug 06, 2014 ]
I see that this product allows audio streaming, but does it allow hands free calling on the phone? [ Rick  Jul 18, 2014 ]

  • This device only offers blue tooth. I supposed you could hear the call through your speakers, but it doesn't have a mic, so I don't know that hands-free would work. I'm only using it for blue tooth music to my car radio. [ Bryan   Jul 21, 2014 ]
  • Nope. Just audio streaming. [ GERALD   Jul 19, 2014 ]
  • No, it doesn't. From my iPhone, it streams my music, but not calls or Siri. I wish I'd asked that question before I bought it. Still, it does a perfect job of streaming audio. Less useful for the car, more useful for, say, a boat.. [ Bradley   Jul 19, 2014 ]
  • I only use this for streaming music but since there isn't a microphone I'm not sure how you could use this for hands free calling. Works great for streaming music. [ MIchael   Jul 19, 2014 ]
  • No-it is dedicated to streaming audio. It does a great job! [ David   Jul 19, 2014 ]
  • I use this on my motorcycle, so as such, I haven't tried that... [ Ray   Jul 19, 2014 ]
  • Unfortunately, it does not answer calls. That was the reason that I purchased it. [ Don   Jul 19, 2014 ]
