Overview

Our take on the JVC KD-X340BTS

If you get your music from a device instead of a disc, you need a receiver that's made for the way you play your tunes. JVC's KD-X340BTS digital media receiver features built-in Bluetooth connectivity, a USB port, and an aux input, plus you can use a compatible phone to control whatever the receiver's doing. You can even add a SiriusXM satellite radio tuner (sold separately) and expand your entertainment horizons even more.

Made for the way you play

If you get your music from a device instead of a disc, you need a receiver that's made for the way you play your tunes. JVC's KD-X340BTS digital media receiver features built-in Bluetooth connectivity, a USB port, and an aux input, plus you can use a compatible phone to control whatever the receiver's doing. You can even add a SiriusXM satellite radio tuner (sold separately) and expand your entertainment horizons even more.

Ready for your Android™ phone

Android® users can control Pandora® right from the stereo through the Bluetooth connection — no wires needed. JVC's remote control app lets you use your compatible Android phone's touchscreen to control the action using finger swipes and gestures. With your Android phone safely attached to a mount, you can reach down and skip a track without taking your eyes off the road. You can also control your Pandora and iHeartRadio stations usng your phone or the receiver itself.

Great with your iPhone®, too

If you're an iPhone® user, this receiver gives you more than wireless control — you get voice control, too. Talk to Siri® Eyes Free technology to make calls, choose music, get directions, and more. Anything you can do with Siri can be done with this receiver.

Experience satellite radio

If you're a satellite radio fan, you can connect a SiriusXM® tuner (sold separately) and start enjoying the wide variety of music, sports, news, and entertainment available. If you haven't experienced satellite radio, you'll be blown away by the incredible selection of music and more that comes with your subscription. Plus, you can drive all the way across the USA without losing your favorite channels.

Tune your music the way you like it

The KD-X340BTS plays MP3, WMA, AAC, WAV, and even FLAC files, so you'll be able to enjoy all your tunes when you travel. You'll find a wide array of sound-shaping tools, including Sound Response to boost frequencies in digital files, Space Enhancement to match the sound to the size of your car, and a 13-band graphic equalizer. The 24-bit DAC brings the best out of your tunes, and the Volume Link EQ boosts specific frequencies in the audio signal to compensate for road noise.

Bluetooth® made easy

Automatic pairing makes it a lot easier to enjoy hands-free calling and wireless audio streaming, no matter what kind of phone you're using.

Expand your system for sweeter sound

The KD-X340BTS gives you three sets of preamp outputs, which really comes in handy when you add amplifiers and a sub to your car audio system. Even if you're not planning to do that right away, it's always smart to invest in a receiver you can grow with. You can also pair two phones at once, so you don't have to choose between the personal phone and the work phone when you're driving.

A charging connection

With your smartphone connected to the KD-X340BTS, you can listen to your phone's internal memory as one source and access its microSD card as another. You'll also appreciate the USB port's powerful 1.5-amp charging capability.

Want to keep your car's steering wheel audio controls?

In most cars, you'll need an adapter to retain those controls with this car stereo. Connect a few wires, then program the adapter for your particular car and radio, and you'll retain the convenience of your steering wheel controls. You'll see the adapters that work with your vehicle when you add this receiver to your cart.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

Sweet radio! A lot of functions. Gets a bit messy but if you chill in the vehicle a bit and play with it, it cleans up nicely.

    Built-in Bluetooth

    Bluetooth Technology: The JVC KD-X340BTS is equipped with built-in Bluetooth 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 Profiles:

    • 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 JVC KD-X340BTS. Check here for the latest Bluetooth compatibility information.

    Multi-Device Pairing w/ Dual Phone Connection: You can pair up to ten Bluetooth-enabled devices to the JVC head unit, with a maximum of two Bluetooth phones and one Bluetooth audio device connected at one time, making it easier to switch between devices. When an already paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units.

    • Secure Simple Pairing (SSP): With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the JVC KD-X340BTS without having to enter pin codes or go through complicated settings.
    • Auto Pairing (via USB):  You can even pair your Apple iPhone (iOS 5+) or Android smartphone (running JVC Music Play App) by simply connecting it to the JVC head unit via USB and following a single prompt on the head unit's display.

    Bluetooth Hands-Free Communication (w/ External Mic): The head unit supports Bluetooth hands-free communication for your Bluetooth enabled mobile phone. And thanks to the latest Hands-Free Profile (HFP 1.6) with wideband speech capability, the KD-X340BTS provides more natural sound quality and details during wireless calls. The controls of the KD-X340BTS can be used to dial a number, answer an in-coming call, or end a call. The unit also includes an external microphone (with mounting bracket) 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 KD-X340BTS 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 KD-X340BTS, 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 front-panel rotary dial.
      • Preset Dialing: You can store up to 6 contacts in the memory of this unit for speed dialing.
      • Phone Book: You can download phone book data from your mobile phone to the digital media receiver. You can then dial a contact within the phonebook from the head unit's front-panel controls. Your phonebook can be searched alphabetically or numerically.
      • 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 once you have activated the voice dialing function from the head unit's front-panel. 

    Wireless Audio Streaming: The JVC KD-X340BTS supports wireless audio playback (AD2P) and control (AVRCP) of a Bluetooth-enabled smartphone or audio player, plus song/artist information display. 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 JVC KD-X340BTS for playback.

    • SBC + AAC Codecs: In addition to support for the standard SBC Bluetooth audio codec, the KD-X340BTS offers support of AAC.  By supporting AAC, the KD-X340BTS 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 KD-X340BTS 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 resume.

    Siri Eyes Free Control: When paired to an iPhone with Siri via Bluetooth, the JVC KD-X340BTS has the ability to access Siri through its front-panel control and external microphone. Simply press the "phone command" button on the KD-X340BTS to engage Siri and use the 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 head unit and its microphone. You can even 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 Bluetooth; the head unit's audio is attenuated while Siri provides audible directions.

    Note: The head unit will only display hands-free calling and Bluetooth audio information (all other functions of Siri are only audible through the KD-X340BTS; visual data will still need to be viewed from your iPhone device).

    Audio Section

    24 Bit D/A Converter: The JVC KD-X340BTS utilizes a 24-bit digital to analog converter for superior sound quality.

    MOSFET Amplifier: The JVC KD-X340BTS is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the KD-X340BTS are as follows:

    • Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)
    • Maximum Output Power: 50 watts x 4 channels (200 total watts)

    Amp Gain: When you are using the KD-X340BTS with factory speakers (or those rated to less than 50 watts peak), the Amplifier Gain Control can limit the amount of power being sent to those speakers. When the Amp Gain Control is set to "low," the volume control ranges from 0 (minimum) to 25 (maximum). When using speakers rated higher than 50 watts peak, you can set the Amp Gain Control to "high," and the volume control will range from 0 to 35.

    4V/6CH Preamp Outputs + Sub Control: The KD-X340BTS is equipped with three pair of 4V preamp outputs (Front, Rear, & Sub). The Front & Rear preamp outputs offer fade control, while the Sub outputs are non-fading. The Sub preamp outputs also offer independent level control (-50 to +10).

    Subwoofer Speaker Connection: You can connect a subwoofer to this head unit without the need of a separate power amplifier.
