GOgroove SMARTmini BT ADVANCED Wireless In-Car Bluetooth FM Transmitter with Charging, Music Control and Hands-Free Calling for ANDROID, iPhone, Blackberry and Windows Smartphones
I love this gadget! It has been a lifesaver or me because I don't like driving and talking on the phone at the same time, I always pulled off the road to take the call or miss it. I love that I can answer the phone over the speakers in the car now if I need to. It's very clear and the unit is very simple to set up.  For me, the bonus is the ability to listen to my favorite music and music apps for my radio stations that I like. I don't know why I didn't buy this sooner!
