Built-in Bluetooth

Bluetooth 3.0: The Kenwood DPX503BT is equipped with
built-in Bluetooth (ver. 3.0) allowing you to make and receive phone calls
wirelessly through the receiver; as well as stream music wirelessly from your
smartphone to the head unit. 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

  • Hands-Free Communication: HFP 1.6 (Hands Free Profile),
    PBAB 1.0 (Phone Book Access Profile).
  • Audio Streaming: A2DP 1.2 (Advanced Audio Distribution
    Profile), AVRCP 1.5 (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 DPX503BT. Visit

Kenwood’s Support Site
for a complete list of compatible Bluetooth
enabled phones.

SSP & USB Pairing: With Secure Simple Pairing (SSP), you can
easily pair a Bluetooth enabled phone to the Kenwood DPX503BT without having
to enter pin codes or go through complicated settings. You can even pair your
Apple iPhone (iOS 5+) or Android smartphone (running Kenwood Music Play App) by
simply connecting it to the Kenwood head unit via USB and following a single
prompt on the head unit’s display.

  • Dual Phone Connection: Thanks to the Dual Phone
    Connection feature, two Bluetooth-enabled phones can remain connected to the
    Kenwood receiver. This means you can an answer an incoming call from either
    phone from the head unit. Also, both of your phone’s contact lists are
    downloaded to the receiver. To make a call from one of the phones using the
    Kenwood receiver, you simply have to select Phone 1 or Phone 2 on the head
    unit’s front-panel.
  • Music Mix: The new Music Mix feature allows five
    Bluetooth audio source devices to be connected to the Kenwood receiver at
    one time, so you can switch between Bluetooth playback sources a lot easier
    and quicker. While “BT Audio” source is selected on the head unit, you can
    simply press the music playback button on your connected Bluetooth source
    devices to switch between devices and begin music playback. However, you
    cannot stream audio from two different Bluetooth audio source devices at the
    same time or combine music libraries or playlists from two different
    connected devices.

Note: You can pair up to five Bluetooth-enabled devices to
the Kenwood head unit. When an already paired Bluetooth device is in close
proximity to the receiver, the auto connection function automatically pairs
the two units.

Bluetooth Hands-Free Communication (w/ External Mic): The head unit supports
Bluetooth hands-free communication for your Bluetooth enabled mobile phone. The
controls of the DPX503BT 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 DPX503BT 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.
  • Dialing a Number: Using the DPX503BT, you can dial a
    phone number in one of the following ways:

    • Enter Phone #: Allows you to directly
      dial a phone number up to 32 digits from the head unit’s control knob or
      remote control.
    • Preset Dial: Allows you to register up
      to 6 phone numbers for quick dialing. The preset numbers can be accessed
      from the head unit’s front-panel controls.
    • Phone Book: You can download phone book data from your
      mobile phone to the
      DPX503BT. You can then dial a contact within the phonebook from the
      head unit’s front-panel controls. Contacts are categorized as Home,
      Office, Mobile, Other, or General.
    • Call History: The Call History is a list of calls
      that have originated from and were received by this unit that you can
      dial. You can select Outgoing, Incoming, or Missed calls.
    • Voice Dialing: If your mobile phone supports voice
      recognition, then you can dial out by voice command. Simply speak into
      the included microphone.

External Mic: 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, noise
cancellation, and echo 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.

Wireless Audio Streaming: The Kenwood DPX503BT supports
wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth-enabled
smartphone or audio player. You are able to stream your
stored music library on your Bluetooth-enabled smartphone, as well as music
apps downloaded on your smartphone to the Kenwood DPX503BT for playback.

  • SBC + AAC Codecs: In addition to support for the
    standard SBC Bluetooth audio codec, the DPX503BT offers support of AAC.
    By supporting AAC, the DPX503BT offers better audio performance of the
    music streamed from your Apple iPod, iPhone, or iPad.
  • Advanced Music Browsing: In addition to basic playback
    functions (Play/Pause, FF/RW, Skip, Random/Repeat), the DPX503BT lets you
    browse your stored music by Playlist, Artist, Album, Song, etc. (AVRCP 1.4
    phones only; which includes Android 4.0+ and iPhone 5.0+).
  • Song/Artist Information: The head unit will also
    display your stored music and music app’s song information; such as Artist
    name and Song/Album title (not compatible with all apps).

Note: When an incoming call or outgoing call is in progress
from your Bluetooth enabled mobile phone, audio streaming will be paused so
you can take your call. Once the call is finished, your streaming music will

included microphone to communicate with Siri. Siri’s voice will heard through
your vehicle’s speakers. All Siri functions including hands-free calling, music
search, setting reminders, text-messaging, audible navigation, and more can be
done through the DPX503BT and its microphone. You even can ask Siri to get
directions to a destination and the turn-by-turn instructions will heard through
your vehicle’s speakers, while the on-screen map still displays on your iPhone
with Siri. The head unit’s audio is attenuated while Siri provides audible

Note: The head unit’s display will only indicate hands-free
calling and Bluetooth audio information (all other functions of Siri are
only audible through the Kenwood DPX503BT; visual data will still need to
be viewed from your iPhone device).

Android Open Accessory 2.0 (AOA 2.0) Connectivity:
The Kenwood DPX503BT’s front-panel USB port lets you connect
select Android (OS 4.1+) smartphones that support AOA 2.0 for music playback.
Kenwood does not guarantee operation with all Android devices, regardless of
operating system. There are
two Android AOA 2.0 modes to choose from based on what content you want to
listen to and how you want to control it.

  • Hand Mode: The Kenwood DPX503BT
    supports Android Open Accessory 2.0 (AOA 2.0), which lets  you connect
    your Android smartphone (OS 4.1+) to the DPX503BT’s front-panel USB port and
    listen to stored music and music apps from your Android device through the
    Kenwood head unit. You’ll be able to control basic playback functions such
    as Play/Pause and Previous/Next Track. Other advanced music navigation will
    still be done from your Android smartphone’s touchscreen. In this mode, the
    head unit will not display song/artist information; only “Hand Mode” will
    show up on display. You’ll continue to view song/artist information from the
    Android device’s touchscreen. You’ll also still be able to access other
    functions and applications from your Android smartphone’s touchscreen, while
    listening to music through the head unit. If you make a call or answer a
    call from your smartphone while listening to music in this mode, the music
    will pause until you are finished with the call and then start back up again.
  • Browse Mode (via Kenwood Music Play App): Downloading the

    Kenwood Music Play app
    onto your Android (OS 4.1+) smartphone with AOA
    2.0 support not only allows you to listen to stored music from your Android
    device through the Kenwood CD receiver connected via USB, but it also lets
    you browse your Android smartphone’s music library from the head unit’s
    front-panel controls. You can browse your store music library by Playlist,
    Artist, Song, Album, or Genre. The contents of a Playlist or Category can be
    searched alphabetically or numerically; you can even skip through the stored
    music files in specific increments (0.5/1/5/10%). You can also control
    Play/Pause and Previous/Next track from the head unit. In addition, the head
    unit will display song/artist information. You can exit the Kenwood Music
    Play app to access other functions and applications of your Android
    smartphone, while your stored music library is still playing through your
    head unit. If you make a call or answer a call from your smartphone while
    listening to music in this mode, the music will pause until you are finished
    with the call and then start back up again.

iPhone Direct Connection: The Kenwood DPX503BT’s
front-panel USB port can be used to connect your Lightning Apple device or 30-pin
iPhone 4S to the head unit. The USB connection allows for
playback of stored music and music apps on your iPod or iPhone through Kenwood

    basic playback functions (such as Play/Pause, Previous/Next Track) from
    stored music and select music apps streamed to your iPhone. You can also
    choose to control your Apple device from its own touchscreen, instead of the
    head unit.
  • Song/Artist Info Display: The DPX503BT will display
    your iPod/iPhone’s music file information such as Track number, Elapsed
    playing time, Artist name, Song title, and Album title.

road noise, and a Stage EQ for better imaging. Separate EQ settings and EQ
presets can be stored for each source or you can apply one EQ preset or curve to
all sources.

  • Preset EQ: The integrated equalizer offers 8 preset
    sound modes (Rock, Pops, Easy, Top 40, Jazz, Natural, Drive EQ, or User)
    suitable for the music genre of your choice.
  • 13-Band EQ: The User mode allows you to manually adjust
    the head unit’s 13-band EQ (62.5Hz, 100Hz, 160Hz, 250Hz, 400Hz, 630Hz, 1kHz,

    better imaging inside your vehicle.

Audio Settings: The Kenwood DPX503BT offers a variety of
audio settings to further enhance your music listening experience.

  • Sound Reconstruction: When MP3, WMA, AAC 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.
  • Space Enhancer & Sound Realizer: The Spacer Enhancer widens the
    soundstage inside your vehicle, while the Sound Realizer makes your music
    sound more realistic.
  • Loudness, Bass Boost & Bass Extension: The Loudness
    feature boosts low and high frequencies to produce a well-balanced sound at
    a low volume level. The unit’s Bass Boost enhances low bass frequencies at
    any volume level. There is also a Bass Extension feature which further
    enhances the unit’s bass output at extremely low frequencies.
  • 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 -15
    to +6.

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