Variable Color Illumination: The Kenwood Excelon KDC-X399 features variable color display and 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 same color setting is applied to both the display and buttons. The Kenwood logo and eject button remain red.
Text Scroll: The KDC-162 will display song/artist information text from CD, USB, iPod, and Android. You can set the text scrolling feature to three different modes (Auto, Once, or Off) to scroll longer titles across the screen.
Brightness & Dimmer: You can adjust the brightness of the LCD from 0-31. You can also dim (on or off) the display. These setting only affect the LCD and do not affect the button illumination.
12Hr/24Hr Clock: The head unit can be set to display a 12hr or 24hr clock. The unit also displays the day (Sun, Mon, Tue, Wed, Thu, Fri, or Sat). The clock is only displayed when selected and does not display simultaneously with song/artist or station information. The day & time can be selected to remain on, even if the head unit is switched off (as long as the vehicle's key is in the accessory or start position).
Demo Mode: This unit features a Demo mode which can be turned On or Off within the menu.
Wireless Remote Control: The KDC-X399 comes with an IR remote control (RC-406) for wireless operation of the head unit. The remote will control Audio, CD, USB/iPod, and Tuner functions. It is powered by a single CR2025 3V lithium-cell battery (supplied).
- Numeric Keypad: The wireless remote control features a numeric keypad (0-9) which allows direct track access of your music tracks & files (from CD or USB), as well as AM/FM presets.
- Attenuator: The CD receiver features an Attenuator button on the supplied remote control that turns the volume down very quickly with one touch of the button.
Steering Wheel Remote Compatibility: The head unit features an OEM steering wheel remote control input wire (blue/yellow) within the included wiring harness that lets you keep your vehicle's factory radio steering wheel remote controls when used with an optional steering wheel audio control adapter (sold separately). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.
