Once your iPhone is mounted in your car, you can rig it up to radio via the
GOgroove SMARTmini BT. This FM transmitter wirelessly connects (via Bluetooth) so you can listen to all your music on radio frequency. When you get a call, the SMARTmini BT allows you to answer without even having to release the steering wheel. It has an enhanced detection microphone to pick up your voice and it turns the car speakers into a speakerphone. The SMARTmini charges your iPhone, too, so you’ll never be stuck with low battery.
