Brilliant car stereo upgrade for older cars

Written by: Swami from Blacklick, OH on January 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!

Written by: SteveW from Kentucky on September 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.

Cons: Not one that I've found.

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

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.

Fits my application perfectly

Written by: Jim D. from SE Michigan on May 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

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.
