About the JVC KW-AVX640
Talk about making a statement in your dash — JVC's KW-AVX640 DVD receiver sports an ample 6.1" touchscreen monitor you can customize to your heart's content. For example, you can choose from over 30,000 color variations for the knobs and buttons, and even use your own digital photos as the screen's wallpaper. Plus you can detach the faceplate for added security, a feature not often found in DVD receivers.
Got an iPhone®? Add in-dash GPS to the KW-AVX640
You can use your iPhone to put the most up-to-date maps available in your dash. Just download the MotionX-GPS Drive app, connect your iPhone with JVC's KS-U30 cable, and you'll have fingertip access to maps and live traffic.
Unlike factory navigation systems, points of interest (POIs) are integrated with Wikipedia and Facebook, giving you more accurate search results than with pre-loaded navigation. Throw in live traffic and live map updates, and you'll have the most accurate navigation system on the planet. At 99 cents, plus $19.99 for a year's subscription for voice guidance and live traffic, it's a fantastic value, too.
Great for your digital music
Just plug in your iPod® or iPhone® to the USB input, and you can use JVC's responsive touchscreen to tap your way through all your tunes and playlists. Not an iPod user? Just load up a USB drive or a recordable disc with digital files — it's easy to fit dozens of albums on either one, and you can still dive in using the touchscreen.
No matter how you play your music, the KW-AVX640 gives you the tools you need to enjoy it to the fullest. A 3-band parametric EQ gives you pinpoint control over the low, middle, and high frequencies, while a high-pass filter lets you trim extreme low bass out of your car's speakers for better performance. High-powered preamp outputs send a clean signal to your aftermarket amps and subs.
Ready for more
JVC lets you add Bluetooth® hands-free calling and satellite radio reception to this receiver. Check the "Accessories" tab for even more options.
Want to keep your steering wheel controls?
In most vehicles, you can use an adapter to connect your vehicle's steering wheel controls to this JVC stereo. Connect a few wires, then program the adapter for your particular car and the JVC, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.
Compatibility note: Currently the MotionX-GPS Drive app only works in your car with the iPhone4. It'll work on the iPhone 3G and 3GS only as a portable navigator.

Amplifier Gain Control: When you are using the KW-AVX640 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 30 (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 50. The internal amp can also be turned off when all the speakers are powered by outboard amplifiers.
5ch/4V Preamp Outputs: The KW-AVX640 is equipped with 5ch/4.0V preamp outputs (Front, Rear, Subwoofer). The front and rear preamp outputs allow fader control, while the subwoofer preamp output is non-fading.
Subwoofer Controls: You can adjust the KW-AVX640's subwoofer level (-50 to +10) independently from the head unit's main volume control for added bass volume. You can also adjust the subwoofer phase between Normal or Reverse to blend the bass sound better with the rest of the speakers in your system.
Built-in Crossovers: The JVC KW-AVX640 features a built-in high-pass filter for the unit's front & rear speakers, and a low-pass filter for the unit's subwoofer output.
- High-Pass Filter: You can activate a variable high-pass filter (40, 60, 80, 100, 120, 150, 180, 220 Hz or Through) for the unit's front & rear channels (speaker- or preamp-level), so low frequency signals are cut off from your system's front & rear speakers. The front & rear channel's high-pass filters can be set independently of one another.
- Low-Pass Filter: The unit's subwoofer preamp output features a low-pass filter. In order to prevent high-frequencies from being sent to your system's subwoofers, you can set the cutoff frequency of the low-pass filter to 50, 60, 80, 100, 120 Hz or Through.
Speaker Select: You can select which type & size of speaker you have connected to the head unit. Choose from Standard (OEM/Factory), Narrow (4"/5"), Middle (6"/5x7"/6x8"), Wide (6x9").
Pro EQ: The KW-AVX640 is equipped with JVC's Pro EQ. The integrated equalizer offers 8 preset sound modes (Flat, Natural, Dynamic, Vocal Boost, Bass Boost, Vibrant, and User) suitable for the music genre of your choice. The User mode allows you to manually adjust the head unit's 3-band parametric EQ (Frequency, Level, and Q-Factor).
|Bass||60, 80, 100, 150 Hz||+/- 10 dB (-5 to +5)||1.0, 1.25, 1.5, 2.0|
|Midrange||0.5, 1.0, 1.5, 2.0 kHz||+/- 10 dB (-5 to +5)||1.0, 2.0|
|Treble||10.0, 12.5, 15.0, 17.5 khz||+/- 10 dB (-5 to +5)||Fixed|
Note: The audio adjustments are memorized for each source until you adjust the sound again.
Loud (Loudness): This feature boosts low and high frequencies to produce a well-balanced sound at a low volume level. You can set the Loudness to On or Off.
Dynamic Range Compression: This function reduces a Dolby Digital soundtrack's dynamic range so you can hear quieter dialog without being overwhelmed by loud sections. You can choose a setting of Auto or On.
Volume Adjust: The input level of each source (other than FM) is adjustable relative to the FM radio volume, so there isn't a significant volume difference when changing sources. Each source is individually adjustable from -15 to +6.
