Great reviews. I picked one up for my car with bluetooth but no AD2P. aptX capability makes it attractive to pair with my HTC One. Other products implementing aptX codec (according to Wikipedia):
-Samsung Galaxy S and Note smartphones, starting with 2012 models
-HTC One series smartphones
-Motorola Droid RAZR Android phones
-Advance Acoustic WTX-500
-SENNHEISER MM 400 X
Cars that do not have a Bluetooth system factory installed very frequently have a "buzz" or "hum" in electrical system once a device like this is plugged in for audio (noise can be heard through the speakers).
If you hear this, it is 99% chance your problem will go away if you buy a "ground loop isolator". It's a ~$10 device that plugs in before the audio AUX port on your stereo.
Cars both cheap and expensive can have this problem. Just spend $10 and get it, okay?
Just put your volume up for your music and you won't hear it.
Don't buy this if you own a BMW E46, it won't work and will disable your aux input!
