El Kameleon JVC EXAD KD-AVX77 Media Player Review

by The Review CrewSeptember 23, 2010

When we last saw JVC’s El Kameleon car audio receiver, we awarded it our Editors’ Choice award for its innovative interface and expandability. However, we wished that the unit featured a touch screen instead of a touch pad.

With the new El Kameleon KD-AVX77, we get our wish. The new El Kameleon features a superwide touch screen that fills up its entire single-DIN faceplate. But is a bigger screen always better?

The superwide screen is awkward for DVD playback, but allows for a fantastic level of customization. You can download custom backgrounds, adjust text and button color and design, and even customize the virtual button layout.

Design
The KD-AVX77 is a single DIN unit with a detachable faceplate. The face is almost completely devoid of physical controls, featuring only a Power/Attenuate button at the top right corner and a button to eject the faceplate at the lower right corner.

The rest of the KD-AVX77’s faceplate is occupied by a 5.4-inch superwide (3.32:1 aspect ratio) touch-screen display with a resolution of 800 pixels by 240 pixels. Frankly, a screen this wide is of limited use for displaying DVD movies, because very few DVDs are encoded in a supercinemascope aspect ratio. As a result, movies viewed on the KD-AVX77’s screen end up cropped, stretched, or just scaled down with black borders.

The display features a proximity sensor that can be used to, for example, pop up the hidden onscreen controls when your hand approaches the screen during DVD playback. The system can be set to hide the interface buttons by default or black out the inactive screen and respond to proximity or touch.

However, where the El Kameleon’s touch screen comes into its own is with the customizable interface. You are able to choose different backgrounds, and virtual button layouts. The KD-AVX77 also features touch gestures for basic commands, such as swirling a finger to quickly raise or lower the volume or swiping horizontally to skip back or forward.

Installation
The KD-AVX77 El Kameleon fits into a standard single-DIN space that many vehicles reserve for car stereos. Basic installation involves making the standard wiring harness connections for power, speakers, etc. Video playback is only enabled when the vehicle is parked, so the e-brake signal lead must be tapped during installation. Additionally, the USB cable pigtail must be routed, as well as the microphone for hands-free calling.

Audio RCA preamp outputs, for stereo front and rear and dedicated center channel and subwoofer outputs, allow for the use of external amplifiers for 5.1 surround sound. A video output and a secondary stereo RCA output allow for the connection of external monitors or a rear-seat entertainment system. A video input either works in conjunction with a reverse-gear signal lead to connect an optional rearview camera, or in conjunction with a stereo RCA line input to add an external video player. Finally, an OE remote input allows for the use of some vehicles’ steering wheel switchgear, with the addition of an optional control box.

The KD-AVX77’s multiple AV inputs and outputs and the AM/FM radio antenna input are all on pigtails and cannot be removed from the device, which means that even if you’re not using a ton of input and output options, you’ll have a lot of cables to cram behind the unit, so make sure you have enough clearance to allow for adequate cooling.
