Make calls on the move and enjoy clear conversation at both ends of the line. Safe, convenient and hands-free. Bluetooth connects your phone and car kit so you can make and answer calls safely while driving. Hands-free calling uses the car kit speakers and microphone. And it works even if your phone's not docked. Clip the extendable microphone to the sun visor or a-pillar in your car to bring it closer. With less background noise, your conversations will be even clearer. A built-in 2 watt speaker brings quality audio to your car. Hear hands-free calls and navigation instructions loud and clear with sound boost. A convenient adjustable top means the cradle will fit your iPhone with or without its cover. Fast charges your phone while you're on the go.
