    • Windows PC (10/8.1/8/7/Vista/XP/2000) or Mac OS X (Mojave [10.14], HighSierra [10.13], Sierra [10.12], El-Capitan [10.11])

IPX5-Rated: Exceeding expectations, HDHU.14Si was subjected to testing above and beyond industry standards, proving its suitability in harsh riding conditions for long-term use. As a result, HDHU.14Si earned an Ingress Protection (IP) water-resistant rating of IPX5, protecting itself from practically any weather condition you’ll ride in, even after a quick trip to the bike wash. Important factors like an optically bonded LCD screen, sonically welded ABS assemblies, conformal coated circuits, silicone gaskets, as well as UV protection ensure the HDHU.14Si performs reliably for years to come.

7″ Capacitive Touchscreen: The HDHU.14Si features a fixed 7″ capacitive touchscreen LCD monitor. The screen has a resolution of 1024 x 600 (614,400 total pixels). The capacitive touchscreen provides a high contrast ratio, crystal clear display, and vivid text; as well as highly responsive touchscreen operation. Touchscreen operations include touch, swipe, and drag.

  • Wallpaper: You can select between five preset wallpapers (backgrounds), or you can upload a custom image via a USB thumbdrive for the head unit’s wallpaper (background).
  • Illumination: You can manually adjust the capacitive touchscreen monitor’s brightness for day and nighttime viewing. You can also setup the unit to have the display dim when you turn your motorcycle’s lights on and then brighten when the lights are turned off.

Touch-Sensitive Buttons: In addition to the 7″ capacitive touchscreen, the HDHU.14Si offers a total of six touch-sensitive buttons (three on either side of the touchscreen) for operation of commonly used functions – such as Apple CarPlay/Android Auto Launch, Voice Recognition (for CarPlay or Android Auto), Power/Mute, Home/Menu, and Volume Up/Down. The buttons’ illumination can be set to White, Red, Yellow, Blue, Purple, Green, Light Green, Custom (Off), or Auto (On). The Custom (Off) mode allows you to create your own illumination color, while the Auto (On) setting cycles through all available color presets.

Apple & Android Integration

Apple CarPlay: The HDHU.14Si digital media receiver retains your motorcycle’s factory OEM installed USB port, allowing you to connect an Apple iPhone 5 or newer (iOS 7.1+) with Apple CarPlay. Apple CarPlay is a smarter, safer way to use your compatible iPhone in the car, while you stay focused on the road. Apple CarPlay takes the things you want to do with your iPhone while driving and integrates them into the HDHU.14Si. Apple CarPlay offers an incredibly intuitive way to make calls, view maps, listen to music, and access messages from your compatible iPhone through the HDHU.14Si in-dash receiver. With Apple CarPlay, you can control these functions from the HDHU.14Si receiver’s 7″ touchscreen or activate Siri for minimized distraction.

  • Maps: Through Apple CarPlay, the power and simplicity of Apple Maps comes to your dashboard; complete with turn-by-turn direction, traffic conditions, and estimated travel time. You can enter a new destination or choose a favorite or recent destination using the head unit’s touchscreen or by simply asking Siri. CarPlay can also predict where you most likely want to go using addresses from your email, text messages, contacts, and calendars. If you have iOS 12.0 or newer on your iPhone with the latest version of Google Maps or Waze, you can choose to navigate via Google Maps or Waze instead of CarPlay. Google Maps and Waze do not support Siri voice control, but will have their own proprietary voice control function which has to be accessed through a touchscreen icon on the receiver.
  • Phone: With Apple CarPlay, you can use the HDHU.14Si’s interactive touchscreen or ask Siri to make calls, return calls, and check voicemail. To dial a phone number, simply tap the “Phone” icon and Siri will ask you who you want to call. Using the touchscreen you can manually enter a phone number from the on-screen keypad, scroll through contacts, or select from recent and miss calls. In addition, you get access to your voicemails via touchscreen and Siri. When a call comes in, simply tap the “Phone” icon to answer. You’ll carry on your side of the conversation through the included external microphone, while the other party is heard through your vehicle’s speakers. You can emphasize or weaken the volume level the microphone. You can also select which car speaker outputs the caller audio; you can select All, Front-Left, Front-Right, or Front-Left/Right.
  • Text Messages: Apple CarPlay also lets you enjoy a better and safer way of text messaging with friends and family when you’re on the road, through the receiver and Siri. Through your voice commands, Siri can send, read, and reply to your text messages so that you never have to glance at your phone while behind the wheel. When a new message comes in a banner will come across the screen and Siri will read back the message for you. Text messages cannot be read or typed from the head unit’s touchscreen to prevent driver distraction.
  • Music Library: CarPlay lets you access your music in your iPhone’s music library, plus iTunes radio from the HDHU.14Si. You can browse your music by Playlist, Artist, Song, etc.. just like you would on your iPhone from the HDHU.14Si’s touchscreen. You can also use Siri to find and play back your music. The HDHU.14Si’s touchscreen will display song/artist information, as well as album art in the background.

Control them from the head unit’s touchscreen or Siri just like you would from your iPhone. Your iPhone’s touchscreen remains unlocked during CarPlay connection, so you are able to access additional music apps and listen to them through the receiver; however these apps offer no control or display information from the head unit’s touchscreen.
  • Apple HomeKit Compatible: CarPlay now supports control of Apple HomeKit enabled devices (sold separately) through Siri. Using CarPlay in your vehicle, you can ask Siri to close or open your garage door, turn on or off home lighting, increase or decrease the temperature of your thermostat, as well as control select functions of other Apple HomeKit enabled devices and appliances.
