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?)

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.

Works Awesome

Great way to play iPhone music through the audio system in my truck - with no wires! Also has a USB port to connect the phone charger. Works great.

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.

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

Cons: None

Works good

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.

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 ]
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 ]
