Newest 3.5mm Wireless Bluetooth V4.1 Car Home AUX Stereo Audio Music Receiver Handsfree Bluetooth Music Receiver Black Color. I have this in my car. When it works it's great, but it's also a little annoying because each time the power is interrupted (ex: turn your car off), it refuses to automatically re-pair with your device. So you have to mess with it until it finally does. I would rather have one that pairs automatically.
