I chose this product to test if it could help me with my car setup. My car has an auxiliary port but it's placed in an awkward place but very close to the car lighter port. This product helped me simplify the setup as it does support Bluetooth to aux connection among a lot of other functions, some which I will probably not use. For now, just using my phone with Bluetooth but it's great that also supports micro SD card for playback as a second option for playing music. Can't complain at all and the audio quality is very good.
