Belkin AirCast Auto HandsFree compare (car audio Bluetooth adapter)

The Belkin Bluetooth Music Receiver is a cheap and easy way to add wireless audio streaming to any powered speaker system or audio component with a spare input.

For cars with an auxiliary input but no native Bluetooth, the GoGroove SmartMini Aux is an effective means of adding both hands-free call capability and audio streaming from a smartphone.

The Kinivo BTC450 is a good and inexpensive choice for adding Bluetooth to cars with an auxiliary input, but it is short on features.

The Scosche MotorMouth II stereo is a unique product that solves the problem of in-car hands-free calling in a unique way, but its ease of use is highly dependent on your dashboard's configuration.
