The Parrot CK3000 Evolution hands-free Car Kit offers the convenience of voice recognition and outstanding sound quality by using your car's sound system as a receiver. It takes less than an hour for your professional installer to mount the Parrot CK3000 EVOLUTION: electronic box, microphone, keypad. There are no visible wires. Once installed, just turn on the ignition, and you are immediately connected to your Bluetooth enabled cell phone. Even by leaving the mobile phone in its pouch, bag, or case - with Parrot CK3000 EVOLUTION, the driver dictates a name and is immediately dialing the stored contact. The car's speakers transmit the conversation with perfect quality of sound, regardless of the driving conditions (traffic, highway.).
