The JVC KD-R600 is an in-dash car-audio receiver that features a built-in MOSFET amplifier with a 200w max power output. The fifth of six JVC KD A/V head units, the JVC KD-R600 is an upgrade from the JVC KD-R300 in that it includes a Full-Speed USB 2.0 connection with 2-way control and charging for iPod/iPhone(s). In all other ways, however, the KD-R600 is practically a duplicate of its peer. For instance, the KD-R600 is also Bluetooth Compatible, Satellite Radio Ready, and HD Radio Ready. Plus, the KD-R600 features a variable-color illumination display with 30 preset color choices. The KD-R600 also includes a regular AM/FM radio and a CD player that supports traditional CDs, CD-Rs, and CD-RWs, not to mention those outfitted with MP3 & WMA music files. In addition, the KD-R600 sports a front auxiliary input, a wireless remote, a 3-band iEQ, a detachable face, a low-pass filter and subwoofer level control, a 24-bit digital-to-analog converter, and 2-channel preamp outputs. The JVC KD-R600 retails for a slightly more expensive $159.95 (versus $119.95) and comes with a 1 year limited warranty. Additional service plans are available for a fee.
