Touchscreen Display

6.1" Touchscreen Display: The JVC KW-NT300 features a fixed 6.1" wide, 16:9 touchscreen LCD monitor. The screen has a resolution of 800 (H) x 480 (V) x RGB with 1,152,000 total pixels. The touchscreen LCD serves as a video monitor, system information display and touchscreen control panel.

Ultras-Fast Start-Up Time: The JVC KW-NT300 has an ultra-fast start up time of approximately 9.4 seconds from Off to the Map screen or an audio/video source screen.

Hard-Key Controls w/ Variable Button Illumination: In addition to the head unit's touchscreen monitor, the KW-NT300 features a rotary-dial and push-button controls along the left edge of the screen. The hard-key controls provide Power, Source, Eject, Volume, Menu, Map, and AV functions. The JVC KW-NT300 allows you to adjust the unit's hard-key button illumination. It offers 7 color presets (Blue, Aqua, Green, Yellow, Pink, Red, and Purple) for the hard-key button illumination. Additionally, there is a user preset, allowing you to individually adjust the intensity of Red, Green, and Blue from 0 to 31. There is also a "Scan" setting which scans through all of the 7 available preset colors continuously.

Split Screen View: The KW-NT300's screen views can be easily toggled from one to another simply be touching the screen or appropriate button. The Split Screen View mode divides the screen into two screens, with navigation on the left and a control window on the right.  With this Picture-in-Picture type function the head unit can now display the navigation and source screens (or rear-view camera) simultaneously.

Off-Axis Viewing: Use the Off-Axis Viewing feature if the screen is hard to see due to the installation angle or position.

Display Adjustment: You can adjust the contrast, color, tint, and detail level during video playback.

Selectable Aspect Modes: You can choose from four aspect modes for the in-dash display:

• Regular: For 4:3 source material, 4:3 and 16:9 pictures display with black bars on either side (16:9 images are compressed).
• Full: Expands 4:3 pictures horizontally to fill the entire width of the screen, distorting the picture slightly but retaining full image height.
• Auto: The correct aspect mode is automatically chosen based on the incoming signal.

Adjustable Dimmer: When 12 volts is applied to the illumination lead (orange/white) and the dimmer is set to Auto, the display will dim automatically when you turn on your vehicle's exterior or interior lights. The dimmer can also be set to Off (normal brightness at all times), or On (display is always dimmed). You can also manually adjust the display brightness for Day & Nighttime driving.

Parking Brake Detection: To prevent the displaying of video while the vehicle is in motion, the light-green parking brake wire (within 22-pin harness) must be connected to your vehicle's parking brake detection circuit. While the vehicle is in motion (parking brake off), you can still view many of the other display and menu functions. When driving at a speed greater than 3 miles-per-hour, some menu screens are not available.
