6.95" Capacitive Touchscreen: The Kenwood Excelon DDX9904S features a 6.95" widescreen (16:9) capacitive touchscreen LCD with LED backlighting. The LCD touchscreen has a resolution of 800 (H) x 480 (V) x RGB with 1,152,000 total pixels. The capacitive touchscreen LCD provides a high contrast ratio, crystal clear display, and vivid text; as well as highly responsive touchscreen operation. Touchscreen operations include tap, touch & hold, flick left or right, and swipe up or down. The monitor electronically slides down for loading or ejecting a disc. The bottom of the touchscreen monitor can be tilted upward at six different positions to provide the best visibility in your vehicle (you can save any one of these positions to the head unit's memory).

• Custom Home Screen & Shortcuts: You can customize the head unit's Home Screen by rearranging the icons and moving the icons of the seven most sources you use most to this screen. Three programmable shortcut source keys offer a quick jump to your favorite sources
• Background Color & Images: You can choose between nine preset background colors - Blue, Purple, Sky Blue, Yellow, Green, Amber, Red, Pink, White. You can also choose to link the displays color with the unit's front-panel variable color illumination that you set. In addition, there are six preset background images or you can download your own still image (800 x 600) for use as the unit's background from a connected USB thumbdrive.
• Picture Adjustments: You can adjust the LCD touchscreen's backlight, contrast, black level, brightness, and color.

Front-Panel Controls w/ Variable Color Illumination: In addition to the touchscreen controls, the unit includes frequently used buttons along the bottom edge of the screen. You can adjust the head unit's button illumination, as well as display background color from the following preset colors - Blue, Purple, Sky Blue, Yellow, Green, Amber, Red, Pink, White or Scan (Scans through all preset colors). You can also select a custom "User" color that is adjusted between Red, Green, and Blue (values range: 0-31).

Dimmer: The dimmer function will dim the head unit's display & front-panel illumination automatically when your vehicle's light switch is turned On, if you have the unit's orange/white "Illumination" wire connected to your vehicle's headlamp circuit. You can also choose to dim the display manually. The Kenwood logo and eject button remain the same brightness.

Clock & Date: The DVD receiver offers a 12-hour clock & day/month/year display. The clock is visible from any source or menu screen. With your vehicle's key in the accessory or start position, the head unit will continue to display the LCD background image, clock, and button illumination during "Standby" mode. Pressing and holding the Power/Home button turns the unit off completely.

Remote Control: The Kenwood DDX9904S offers compatibility with factory steering wheel controls (adapter sold separately) and is compatible with Kenwood's IR wireless remote control (sold separately) for added convenience.

• Steering Wheel Controls: The head unit features a factory 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).
• Optional Remote Control: The optional Kenwood KNA-RCDV331 IR wireless remote control (113RCDV331, sold separately) unit is designed to operate this Kenwood DVD head unit. The wireless remote controller operates off of two supplied "AAA" batteries. The remote operates off of IR transmission so the KNA-RCDV331 must be pointed at the front-panel of the Kenwood head unit within direct line of sight.
