Bluetooth® Wireless Technology: Built-In (Including Microphone)
With Bluetooth® Wireless Technology already built in KD-AVX33, KD-ADV38 and KD-BT1, expect a secure wireless connection with your portable devices. A maximum of five mobile phones can be registered for hands-free calling. With voice-recognition mobile phones, you can dial by just saying the name in your phone book. The wireless functions work even if your mobile phone is tucked away in your bag or pocket. You can also stream music from a compatible digital audio player for listening on your car audio.

The KD-AVX33, KD-ADV38 and KD-BT1 also feature text messaging. A beep notifies you of incoming text messages, which can then be shown on the screen. You can also transfer your phone book from your mobile phone to the receiver. Up to 5,000 numbers can be stored.
