VIEWTEK -Bluetooth 4.0 Wireless Stereo Music Receiver with Ground Loop Noise Isolator Handsfree Car Kits Bluetooth Receiver Adapter, VIEVL, Black

This is great! I installed this in my 2005 Pacifica and was up and running in less than 5 minutes! Being an older car the stock stereo didn't have bluetooth, but it did have an AUX input... so this device was ideal.A local car stereo dealer wanted nearly $300 to install a new stereo with bluetooth, which would have rendered the stock 6 disk DVD changer in my car useless... for less than 1/10th of the price this device added bluetooth to my car without having to open up the dash, remove my stereo, and make my DVD changer inoperable! Don't be conned by car stereo installers that tell you that you need to replace your stereo to add bluetooth functionality to your existing equipment, they are just trying to make a quick easy buck off your ignorance!I spent some time doing some research on these bluetooth devices and decided to opt for this unit for a couple of reasons:1.) It includes a ground loop noise isolator! The way car electrical systems work ground loop noise is a common issue with many cars. This produces an audible hum that is very annoying! This device eliminates this completely. For testing purposes I tried it without the noise isolator hooked up and noticed a very annoying hum. To buy one of these separately can cost as much as I got this unit for, which includes it! Great value!2.) This unit supports having more than one device connected to it at once. Since both me and my wife are often in the car together this was a must have. This feature works flawlessly, just follow the included directions carefully.3.) Auto-Connect when in range! This is huge. I would hate having to connect my phone manually every time I got in the car and would probably forget more often than not... until my phone started ringing and I needed it connected to use my speakerphone!My experience with using the device has been very positive.I can tell no difference in sound quality with this device over using an AUX cable.Other people can not tell the difference between when I am using this for my speakerphone and me just talking on my regular phone. Unlike other models that I have read about that have issues with echo or tinny sounding speakerphone, this device sounds great.The noise/echo cancellation on this is excellent, there's absolutely no echo on either end of the call, even at high volumes! I was particularly surprised (in a good way) about this!For the money and the features this device has I don't believe there is a better option on the market. Highly recommended.It's also worth noting this device can be added to ANY speakers with a 3.5mm audio input that you want to add bluetooth and speakerphone functionality to, not just car stereos. I'm planning on ordering another soon to use on my surround sound computer speakers to play music on wirelessly, and to use as a speakerphone in my office! Note: You can also use this with speakers or stereos that use RCA inputs instead of 3.5mm inputs (which was the case for my car) with a cheap adapter like this one:  Monoprice 6inch Premium 3.5mm Stereo Female to 2RCA Male 22AWG Cable (Gold Plated) - Black Keep in mind this can be powered by any powered USB port, but will need a USB port in your car. If your car has no USB ports you can use a cigarette lighter charger with USB like this one:  Dbpower Safety Hammer USB Rapid Car Charger 2 Port Intelligent Output 4.8a Dual Port USB Car Adapter Portable Travel Rapid Mini Bullet Charger for Iphone Samsung and Android Devices (Black)

The product works exactly as advertised. It's loud and clear and i have no complaints about it in general except for one thing.There is a loud thumping noise whenever the cell phone audio stops playing. This is most noticeable when i am getting GPS directions. After each phrase, the audio stops and there is a thumping noise similar to the sound of someone tapping on a microphone.For example, if my GPS is running it would sound like this:"At the next traffic light, make a left" *THUMP*"Merge onto the highway in 100 yards" *THUMP*It is quite jarring and it really detracts from this product. I have had other Bluetooth devices in the past and i have never had this issue. I am using a Samsung Galaxy S7 and a Moto G4. They both have this issue. If however i am playing music in the background along with the GPS, no thumping occurs. I suspect this is because this device turns off the amplifier whenever audio stops and that is what causes this thumping. If there is continuous signal, then the internal audio amplifier is always on.**UPDATE: 03/22/17**After this review, DBPOWER contacted me and offered to either refund the product or provide a replacement. I was willing to give their product another shot so I opted for a replacement. (They let me keep the old one) When the product arrived the second time, I experienced the exact same issue in both cars. So i give DBPOWER customer service props for offering to help me out, but at the end of the day, there is only so much you can do with a faulty product.

I have a Kenwood car stereo in my work truck and Kenwood had to be so difficult to make my Galaxy S7 play my music files over the speakers in my cab. I was honestly so mad that I was about to take a hammer and smash that junk Kenwood up and buy a different radio! During my Amazon search for a new radio, this little gem popped up. I read the reviews and decided what the heck, it's cheaper than a new head unit and bought it. Boy am I glad I did! This little beauty connected easily to my phone and is so easy to operate. I love it so much I'm gonna buy 2 more for my personal cars and I have a few Christmas gifts in mind. I know this picture looks rough but it's how I was able to connect it in a concrete truck up out of the way. Do yourself a favor and buy it. You'll love it too!

Well this turned out to be super disappointing. It worked for about a month and then the dial and play/pause button stopped working. It still picks up my music but if I want to change a song or answer a call I have to reach for and mess with my phone...which defeats the whole reason I purchased this product. I don't know whether the one I got is just faulty or what. I thought it was supposed to light up or something too which it never did even right out of the box (I could be wrong about that...unsure). I tried to contact the seller but couldn't find anywhere to contact, so I ended up contacting Amazon and they refunded my money. Maybe the company will see my review and reach out to me...who knows. Very disappointed.
