In order to use Bluetooth wireless technology, your phone must also be Bluetooth compatible and be able to interpret certain profiles. This unit is compatible with the following Bluetooth Profiles:

    • Hands-Free Communication: HFP 1.5 (Hands Free Profile), OPP 1.1 (Object Push Profile), PBAB 1.0 (Phone Book Access Profile).
    • Audio Streaming: A2DP 1.2 (Advanced Audio Distribution Profile), AVRCP 1.3 (Audio/Video Remote Control Profile).
    Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Kenwood KDC-BT318U. Visit Kenwood's Support Site for a complete list of compatible Bluetooth enabled phones.

    Secure Simple Pairing (SSP) + Auto Pairing (for iPhone): With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the Kenwood KDC-BT318U without having to enter pin codes or go through complicated settings. When a paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units. You can pair up to five Bluetooth-enabled devices to the Kenwood head unit with a maximum of two Bluetooth phones and one Bluetooth audio player connected at one time (but only one can be used at a time). You can even pair your Apple iPhone by simply connecting it to the Kenwood head unit via USB and following a single prompt on the head unit's display.

    Bluetooth Hands-Free Communication: The head unit supports Bluetooth hands-free communication for your Bluetooth enabled mobile phone. The controls of the KDC-BT318U can be used to dial a number, answer an in-coming call, or end a call. The unit also includes an external microphone (featuring adjustable gain), so you can carry on your side of the conversation while listening to the caller through your vehicles speakers. During a conversation, you can switch between the Private Mode (talking directly on your cell phone) and the Hands Free Mode. 

    • Answering a Call: When a call comes in, a ring-tone will be heard through your vehicle's speaker and the caller's name or phone number will be displayed. You can answer the call from the head unit's front-panel controls, or setup the head unit to automatically answer the incoming call immediately or after 1-30 seconds. The KDC-BT318U also supports the Call Waiting function, so you can answer another incoming call while suspending the current call you are on. Your compatible cell-phone must also support this feature.

      • Voice Dialing: If your mobile phone supports voice recognition, then you can dial out by voice command. Simply speak into the included microphone.

    Note: The external wired microphone offers improved audio quality versus an integrated microphone, so you can be heard easier over noisy traffic and road noise. You can adjust the volume level and noise cancellation of the microphone without affecting the other sources. The external microphone features an attached 10' cable terminated by a right-angle 3.5mm connector which plugs into the mic input on the rear-panel of the head unit. The microphone offers an integrated mounting bracket which can be clipped to your vehicle's sun-visor or taped to your dash. The external microphone measures 0.525" (diameter) x 1.505" (depth).

    Subwoofer Controls: The Kenwood KDC-BT318U offers the following subwoofer controls, when you have the unit's subwoofer preamp output activated.

    • Low Pass Filter: The receiver features a built-in Low Pass Filter control for the preamp-output, when the output is set to Subwoofer. You can select from 85 Hz, 120 Hz, 160 Hz, or off.
    • Subwoofer Phase: You can adjust the phase of the subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).
    • Subwoofer Level: Once the Subwoofer preamp output is activated, you can independently control the subwoofer preamp output level (-15 to +15) from the CD receiver.

    Speaker Settings: The Speaker Setting function tailors the head unit's audio settings according to the type of speakers in your vehicle. You may select a Speaker Setting of 'SP-Off' (flat/off), 'SP-OEM' (for OEM factory speaker systems), 'SP-6x9/6' (for systems with 6" and 6"x9" speakers), or 'SP-5/4' (for systems with 4" and 5" speakers).

    Preset EQ: Eight EQ curves are preset into memory, allowing you to recall the best preset EQ curve for different types of music. Each preset has its own level settings for bass, midrange, and treble . You can choose from the following preset EQ curves; Rock, Pops, Easy, Top 40, Jazz, Natural, Drive EQ, or User. The Drive EQ mode is an EQ preset that helps reduce road noise. The User mode allows you to manually adjust the head unit's Bass (200Hz) , Midrange (2.5kHz), and Treble (12.5kHz) level from +/- 8dB.

    Note: You can store bass, middle and treble tone settings for each source (CD, AM/FM, Aux, USB, iPod, and Pandora/iHeart Radio).

    Sound Enhancements: The head unit provides further sound enhancements for your car audio system.

    • Bass Boost: The Kenwood CD receiver features a Bass Boost control that can be set to the following levels (BB1, BB2, BB3, or Off).
    • Loudness: This function enhances low and high frequencies to make the sound clearer lower volumes. There are 3 levels (LV1, LV2, or Off).
    • Sound Reconstruction: When MP3 or WMA files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Sound Reconstruction function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When Sound Reconstruction is Off, the unit plays the original sound stored in the audio file.

    Volume Offset: The level of each source may be independently adjusted to prevent radical leaps in output volume when switching from one source to another. The available settings range from -8 to 0 (-8 to +8 for Aux source).

    Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    Display Features

    Detachable Face: The Kenwood KDC-BT318U features a single front loading CD face that detaches from the chassis to deter theft. There is no protective face case included. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.

    Single-Line Display: The Kenwood head unit features a single-line, 13-segmented/13-character, white backlit LCD with blue button illumination.

    Brightness & Dimmer: You can dim the LCD illumination to better suit the time of day. You can adjust the maximum brightness of the LCD illumination from 0-31. The button illumination and Kenwood logo does not dim.

    12Hr/24Hr Clock: The head unit can be set to display a 12hr or 24hr clock. The unit also displays the day (Sun, Mon, Tue, Wed, Thu, Fri, or Sat). With your vehicle's key in the accessory or start position, the head unit continues to display the clock and button illumination during Standby mode. Pressing and holding the source button turns the unit off completely.

    Demo Mode: This unit features a Demo mode which can be turned On or Off within the menu.

    Remote Control

    Wireless Remote Control: The KDC-BT318U comes with an IR remote control (RC-406) for wireless operation of the head unit. The remote will control Audio, CD, USB, and Tuner functions. It is powered by a single CR2025 3V lithium-cell battery (supplied).

    • Numeric Keypad: The wireless remote control features a numeric keypad (0-9) which allows direct track access of your music tracks & files (from CD or USB), as well as AM/FM presets.
    • Attenuator: The CD receiver features an Attenuator button on the supplied remote control that turns the volume down very quickly with one touch of the button.

    Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input wire (blue/yellow) within the included wiring harness that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.
