I would recommend to the value conscious DIYers who wants to keep existing car audio, but want to add Bluetooth telephony and audio.

You can set up in different ways, but I choose to use built-in amplifier which is less powerful than my car audio. The quality of audio over Bluetooth is very decent, but probably not for audiophiles. I haven't tried built-in voice-recognition, but I can activate voice-recognition on my smart phone by pressing call button on the remote. Voice quality is good and loud enough. During hwy driving, however, voice-recognition was struggling though conversation was not an issue. The wireless remote is very convenient though hope it was bit more responsive.

I purchased a wiring harness for my car from another shop which simplified installation a lot. Experience may vary depending on the model of your car.

All in all, very decent product.

Overall I am very pleased with the Parrot MKi9100. My only issue is the LCD display being very difficult to see in any kind of sunlight even with the brightness turned all the way up. Technically you don't need to SEE the display to use its functionality so I suppose it's not an issue. Other than that, it's AWESOME! Wireless remote, Bluetooth calls & streaming audio! Wired aux/iPod inputs come in handy too! I get in the car and my iphone connect automatically. If I start the ipod it streams automatically, same with Pandora/Sirius XM/iHeartRadio
