Talk on the phone hands-free with your compatible Alpine stereo and the KCA-100BT Bluetooth adapter interface. It works with 2004-up Ai-NET Alpine stereos, allowing you to make and receive calls via your Bluetooth capable cell phone.

A one-time process prepares your phone for use with the KCA-100BT. Once the system has been set up, the Bluetooth connection initializes automatically as soon as you get in the car. From there, you get the safety and convenience of a mobile speakerphone.

The KCA-100BT includes a call control button that mounts on the dash, allowing you to pick up and end calls with one-touch convenience. A visor clip microphone is also included. Warranty: 1 year.

Note: If you're planning on adding this Bluetooth adapter interface with a system that includes a direct-connect XM or SIRIUS satellite radio purchased before June 2006, please call 1-888-955-6000 before you buy for compatibility information.

Note: Bluetooth compatibility with this device may vary, depending on your phone and service provider.

Product Research


Overview: The Alpine KCA-100BT Bluetooth Interface allows you to make and receive calls on your Bluetooth-equipped cellular telephone and Apple iPhone through a 2004-up Ai-NET equipped Alpine head unit. The interface includes a microphone and a 3-button remote to assist you in making and answering your calls.

Bluetooth Hands-Free Telephone Feature: With the interface, you can initiate, answer, and end a call on your Bluetooth telephone without touching it. Once the interface is installed and paired with your phone, you can initiate a call by pressing a button on the remote, and dialing the number using a voice tag. Once the other party answers, you can speak to them through the supplied microphone and listen to their voice through your vehicle's speakers. During the call, the head unit mutes the current source being played so you can hear the call (head unit must have telephone mute wire).

Note: If your phone does not support voice tag functionality, you will need to dial the number on the phone handset.

Bluetooth Streaming Audio: You can also listen to Bluetooth streaming audio devices through the interface. Some devices with streaming audio functionality also have command and control protocols, allowing you to use the head unit's preset buttons for play, pause, previous track, and next track commands.

Note: The Apple iPhone does not support Bluetooth wireless music audio streaming.

Microphone: The supplied microphone allows you to use voice tags for dialing, and speak to the other party on the telephone call hands free. The microphone comes with clips and hardware for a variety of mounting options. Dimensions: Diameter=0.538", Length=1.31", Cable Length=9.75'.

Remote: The 3-button remote allows you to initiate, answer, and terminate your phone calls. You can also adjust the volume up or down with the + and - buttons. Dimensions: Width=1.302", Height=0.524", Depth=1.894", Cable Length=9.75'
