I have a mini cooper and an HTC One X. This device allows me to plus the bluetooth stereo clip in my external audio jack and sync all of the music from my phone to my car's stereo. The clarity of the music is great. The only thing that at first was an issue was recharging the stereo clip that I kept leaving on. But now I have a short USB cord that goes from my car phone charger to the stereo clip. Not a problem any longer.
I would recommend this to a friend
