Kenwood's KDC-255U CD receiver delivers solid performance and plenty of features at a pretty nice price.You get variable color illumination for the buttons so you can set the color to match your dash lighting perfectly. The front USB port allows you to control the music on your iPhone® or Android® phone through this Kenwood, and gives you access to SiriusXM, iHeartRadio, Pandora Internet radio, and other apps on your iPhone too.
You can adjust the color on this Kenwood's buttons to match your car's illumination.
Kenwood built impressive amplification into this receiver. You'll notice a dramatic power boost and improved sound quality, even if you still have your factory speakers — with aftermarket speakers, the difference is even more significant. With a 3-band EQ and 3-level bass boost, you can tweak your music to your heart's content, while the Supreme Setting feature enhances the sound of MP3 and WMA files. If you add a powered sub to your system, you can use the sub level control, the low-pass crossover, and the phase setting to adjust your bass.
The easily accessed front-panel minijack input offers a quick connection for portable music players and other audio devices. Or if CDs are more your style, this receiver delivers excellent sound quality, soundstaging, and stereo separation, whether they're produced by your favorite prerecorded CDs or discs that you loaded up with MP3 and WMA files. Your passengers can use the included wireless remote to change tunes, sources, and sound settings.
iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.
Great product I've tried several car stereos in the past but this on is best by far.

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.

Preset EQ: Eight EQ curves are preset into memory, allowing you to recall the best preset EQ curve for different types of music.

Sound Enhancements: The head unit provides further sound enhancements for your car audio system.
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 -8 to 0 (-8 to +8 for Aux source).

AM/FM Tuner: The Kenwood KDC-255U features a built-in AM/FM tuner. You can choose one of four tuning methods: Auto 1 (seek tuning), Auto 2 (cycles through and tunes the selected band's preset stations only with each button press), Manual Tune, or Direct Access (via remote).

Mono Mode: The Mono mode improves the radio's FM reception, but the stereo effect will be lost.
Detachable Face: The Kenwood KDC-255U features a single front loading CD face that detaches from the chassis to deter theft. There is no protective face case included. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.
Fluorescent Display: The Kenwood head unit features a single-line, 11-character, bluish-white backlit fluorescent display.
Variable Color Button Illumination: The Kenwood KDC-255U features variable color button illumination. You can choose from one of 24 preset colors, have the unit scan through all 24 preset colors continuously, or customize your own color (RGB; 0-9). The custom setting allows you to individually adjust the intensity of Red, Green, and Blue (from 0-9) to better match your vehicle's interior lights. The Kenwood logo and eject button remain red.
Display Illumination/Clock Display: When the unit is in Standby mode, the face and button illumination is "keyed." When the Clock Display is turned on and the unit is in Standby mode, the Clock Display is also "keyed." Pressing and holding the source button turns the unit off completely.
Illumination Dimmer: You can manually dim the LCD and button illumination to better suit the time of day. The Kenwood logo and eject button do not dim.
Demo Mode: This unit features a Demo mode which can be turned On or Off within the menu.
Wireless Remote Control: The KDC-255U comes with an IR remote control (RC-406) for wireless operation of the head unit. The remote will control Audio, CD, USB, and Tuner functions. It is powered by a single CR2025 3V lithium-cell battery (supplied).

Yes [ RASHEEN J Nov 17, 2013 ]
My truck windows are lightly tinted and the stereo is read very easily in the day light. [ SIDNEY Nov 16, 2013 ]
No problem seeing the display. You can set it to any color you like. I'm very happy with this unit. [ COLAN L Nov 15, 2013 ]
Yes. It's decently bright and on a sunny day you can see/read it as long as there's no glare directly on the face. [ LEVI Nov 15, 2013 ]
I've never used it on an audiobook before. The Ipod control is mainly meant for pandora and apps such as that. That being said, it does allow the ipod to remain in an unaltered state when paused. I have used an audio file on the pod so this should work the same way. As long as the file recognizes as an MP3 or mp4 it should make a difference as the ipod has no idea the difference between the two. I'd bet that it would work. [ Jerry Dec 17, 2014 ]
It will do the same as if you paused it while listening on headphones or anything else. I would highly recommend making sure your iPod/iPhone is compatible though, my iPhone 5s and my wife's 6 are not...can only listen through an audio jack, so no iPod/iPhone control thought the unit.
