Works amazing well with my car, but it didn't meet 100% of my needs. My car already has hands-free calling, so I wanted this strictly to stream music from my phone through my car speakers, but there is no option to use just the music streaming. Can't knock the product for that though as it isn't advertised to do just that.

There still is a way to do this! When your device is connected to the Kinivio, go into your phones Bluetooth settings and click your cars Hands-free bluetooth option. Once you do this, music will stream from your phone and if you get a call, it will switch over to your cars Hands-free bluetooth. This is a manual process every time, but works for my needs. For reference, I have a Samsung Galaxy S4.

The reason that this is 4 stars is that nearly every review that I have read has stated that you need to buy a ground loop isolator to get this to work without the "humming" noise coming from your speaker. Sure enough, mine made the "humming" noise as well, but once I bought the ground loop isolator, it worked like a champ. I bought this one:

"PAC SNI-1/3.5 3.5-mm Ground Loop Noise Isolator Works with iPod/Zune/iRiver and Others"

If you need another product for your item to work properly, then it should be included. Just my 2 cents.

I have to admit, I LOVE the BTC455.

I previously reviewed the BTC450, and my main criticism of the BTC450 was it did not allow for the simultaneous connection of two Bluetooth devices.

The addition of this feature completes an already excellent product. Before, if you had two people sharing a car who had two different Bluetooth phones or if you just wanted to listen to music from your iPod while also having your phone connected you would need to repair the BTC450 every time with each device. Now, both devices automatically connect, and can be used while the other is not being used.

I am going to briefly go over how multi point functions, as my previous review of the BTC450 still covers all of the BTC455's great features.

1. After you pair both devices, the Kinivo automatically will reconnect to both devices each time you re enter the car.

2. Only one device can be used at a time. For instance, I can not talk on the phone through the BTC455 at the same time someone else is talking on the phone through the BTC455.

3. If you are using a device and listening to music with the BTC455, and a call comes in on another phone, the BTC455 will pull through the phone call if you answer it.

4. The last important point; the buttons on the BTC455 only work with the last active device UNLESS a phone call comes through on another device, in which case you can answer the call with the button on the BTC455.

In concluding my review, the BTC455 is the perfect solution for someone needing to use two devices. Kinivo made the BEST bluetooth receiver.

Having to wait only a year for a truly remarkable product is well worth the wait. In my opinion, Kinivo truly cares about their customers opinion as well as having excellent customer service. Thank You!

Technology is quickly evolving, but many vehicles aren't equipped with this technology. To make your vehicle Bluetooth compatible, it is important to purchase devices like the Kinivo BTC455 Bluetooth Hands-Free Car Kit.

▶ Package Contents
* Kinivo BTC455 Bluetooth Hands-Free Car Kit
* 3.5mm female to male audio extension cable
* Two adhesive mounting discs
* User manual

▶ Accessories
The accessories for this device are two adhesive mounting discs and one 26" inch 3.5mm female to male audio extension cable. The mounting discs are each very thin, with adhesive on both sides. I honestly dislike this method of mounting the disk to any dashboard, as the adhesive on either side won't fare well in weathered conditions, but this issue is easily fixed. For my product, I used super glue and Velcro for my product. The male to female extension cable has a hard plastic casing around both ends, with the female port using the straight design, and male port using the conventional L shaped design. I like the addition of this accessory, but think it isn't very necessary, since most users will have enough slack from the existing audio cable.

▶ Specifications
* Bluetooth Specification: Bluetooth 4.0 with multipoint
* Bluetooth profiles: HSP, HFP, A2DP and AVRCP
* Operating distance: 30 ft (10m) class II
* Power input: DC 12V-24V
* Charging output: DC 5V-1A
* Dimensions: Main unit: 42 x 15 x 42 mm; Car adapter: 24 x 54 x 24 mm

▶ Hardware
The main product is one piece, with the main unit being 1.6" x 1.6" x 0.6 inches, leading through a thick 36" cord to a Y-connector, which splits into two 11.5" cords, leading to the built-in car charger and 3.5mm audio cable.

I was having a lot of problems with the headphone jack into aux approach. Lots of whine and hiss. My car has BT connection for phone, but not for audio (which came the next year). Upgrade module is crazy expensive.

This saved the day.

I connect to both this and the car. In Bluetooth settings for each connection I specify that audio goes to Kinivo, and calls go to the car. It's seamless. Phone rings, audio pauses, and I get the much better audio/mic from the car for phone.

Pairing is immediate when the car starts, no need to push buttons, or flip through phone settings.

The phone audio quality of the Kinivo is passable, but if your car supports phone it's probably much better.

It comes with two double-stick foam mounting adhesive circles. They are not pre-attached, which is great so you can use or not without the backing paper slowly peeling away if you don't mount it to something. I just let it hang loose on center console since all my connections are under the armrest.

The audio quality of this is very good. much better than headphone jack. It could be because of the aptX support in the phone and BT 4.0, but there is no hiss, no whine, and I can't discern artifacts or compression. Songs with wide dynamic range sound excellent.

Voice commands work well, but it only works with phone dialing. Once disabling the call setting in Bluetooth settings, the ability to use voice commands was gone, but I kind of expected that and don't use them anyway. It did work well though.

90 degree angled plug is a plus, so it doesn't bend and slowly break the internal wires, which I had happen before.

Cable length is sufficient to reach most anywhere, and an extension is provided for longer reach.
