The Good The Alpine KCE-400BT allows users to easily add Bluetooth hands-free calling and audio streaming to a compatible Alpine car stereo. Active Echo Cancellation makes calls clear and reduces background noise. Automatic importing of contacts and support for voice dialing makes it quick and easy to initiate calls.

The Bad Contact list updates can take several moments, during which no calls can be made. Installation requires more steps and hardwiring than a standalone Bluetooth speakerphone. When paired to units that don't feature a touch screen, calls are limited to numbers previously saved.

The Bottom Line For users who already own an Alpine car audio receiver, the KCE-400BT offers an easy way to extend the functionality, safety, and usable life of the headunit by adding clear, hands-free calling and wireless audio streaming.

Don't Miss

The Alpine KCE-400BT is part of Alpine's series of add-on modules that, in this case, adds Bluetooth connectivity to receivers that support Alpine's proprietary Ai-NET high-speed connection cable, extending the flexibility of its line of car stereo receivers.

However, the KCE-400BT not only adds hands-free calling technology powered by Parrot--makers of the fantastic Minikit Slim--but it also adds the A2DP and AVRCP audio streaming protocols, effectively giving users a whole extra audio source for their vehicles.

Design
The KCE-400BT consists of a plastic hideaway box with connections for Ai-NET data input, an Ai-NET data cable output for daisy-chaining other Alpine add-on modules, a power connection wire harness, and an external microphone with a gratuitously long cable for mounting near the driver's head.

The KCE-400BT's shell is plastic unlike the metal housing of the TUA-T550HD HD radio receiver tested earlier, which is probably necessitated by the KCE-400BT's internal Bluetooth antenna (the TUA-T550HD used an external antenna).

The unit mounts using included hook and loop adhesive strips and is small enough to fit behind the dash or under a seat. We'd suggest that you test for optimal Bluetooth signal strength before permanently mounting the KCE-400BT.

A person with moderate car stereo installation skills could install the KCE-400BT with simple hand tools in about an hour, depending on the number of body panels that need to be removed to cleanly hide the unit and route the microphone cable.

Once powered up and connected to a compatible Alpine headunit, the KCE-400BT can be found and paired with, using your Bluetooth device.

Features
The primary purpose of the KCE-400BT is to add Bluetooth hands-free calling to compatible Alpine receivers.

Devices are paired using a four-digit PIN. Once paired, the KCE-400BT is able to sync the contact list and the most recently dialed, received, and missed calls. This list is auto updating, so if you make a call outside of the car or add a contact, it will be reflected upon the next pairing.
