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.

Amazing little device, it adds the functionality that I require with such ease. Comes with a short coiled aux cord which worked perfect in my subaru tribes (which has two 12v outlets with the auxiliary port in the middle and it's all stuffed in the center console)

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

Good reviews [ Daniel  May 04, 2017 ]
I am intrigued by the auto on/off feature, its ability to remember the paired device, and that it allows additional charging from the charging port. I hope this device is as advertised... My 2008 vehicle has built-in Bluetooth for phone calls, but not music. Now I have both. [ shane  Oct 17, 2016 ]
Great price and has the features I need. [ John  Apr 17, 2016 ]
It was simple and exactly what I was looking for [ Joseph  Dec 16, 2015 ]
I bought one this summer and it works fantastic. Bought two more for Christmas gifts. Always excellent service and prices from Crutchfield. [ Brian  Dec 08, 2015 ]

5 questions already asked

I only synced one device. It worked fine for 3 months then it died on me [ Francisco  Jan 08, 2015 ]
I'm not 100% sure, but I believe it only pairs to one device at a time. However, there's no code to enter when pairing to phone, so it's quick and easy to do. [ Gregory  Jan 08, 2015 ]
There is no limit. After you sync a device it will remember it each time that device connects. It allows one device to be connected at a time. If you are connected and one of your daughters wants to connect basically turn off your bluetooth, then one of them can connect. [ Trevor  Jan 08, 2015 ]
Sounds great to me but know that my ears have been subjected to 'elevated' volume levels in my younger years (ELO, Moody Blues, Boston, Pink Floyd...) [ LINC  Jan 09, 2017 ]
works great for me. sound is very clear. [ Bryan  Feb 03, 2015 ]
Sound quality is great (for both music and news/talk/sports streaming radio). [ GEOFFREY  Dec 30, 2014 ]
sounds good but mine burned up after a few weeks I would not buy it again since it was a waste to me and my check book [ JASON  Dec 29, 2014 ]
I can't give an opinion on HD sound, but I believe the overall sound quality is great. Used for streaming music from my phone. [ Kevin  Dec 28, 2014 ]
Grrrrreat [ phin  Dec 28, 2014 ]
I am quite pleased with the performance of the Fosgate unit. I've recommended it to friends. [ David  Dec 28, 2014 ]
We can be 30 feet from the receiver and get excellent reception. The quality of your speakers and receiver will have more to do with sound quality than this unit. We have experienced no loss of sound quality. We have been using ours on a boat. [ MIchael  Dec 28, 2014 ]
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  Sep 16, 2014 ]  Staff
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 ]
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 ]
