This guide covers the physical installation and wiring of your WDD-LITE (Wireless Data Display Lite) with any compatible base station: WVC, WVC-LITE, WVC-PRO, or WVC-PRO 6.
Before You Begin
You will need:
- WDD-LITE unit with its included power cable and mounting hardware (flush-mount cradle, adjustable-angle base, and screws)
- A mounted and powered WVC base station
- A suitable mounting location within wireless range of the base station
- Basic hand tools for mounting and an inline fuse holder for the power lead
The WDD-LITE communicates wirelessly with your WVC base station, so the two units do not need to be near each other or share any signal wiring. Only power needs to reach the WDD-LITE.
Choosing a Mounting Location
When selecting where to install the WDD-LITE:
- Wireless range: the display communicates wirelessly with the base station. Mount it within reasonable range. Metal barriers and dense wiring can reduce signal strength.
- Visibility: the AMOLED screen is bright and viewable at wide angles, but position it where you can comfortably see it while driving. The display supports four viewing orientations (two landscape and two portrait), which you set in the menu to match how you mount it; it ships in landscape by default.
- Reach: navigation is by touch, so mount the WDD-LITE within easy reach of your hand for swiping and tapping.
- Avoid heat sources: do not mount directly on or near amplifiers, exhaust components, or other heat-generating equipment, and avoid locations with prolonged direct sun.
Wiring
The WDD-LITE is powered by a simple three-wire connection. There is no signal wiring to run: all communication with the base station is wireless.
| Wire | Connect To | Description |
|---|---|---|
| Yellow (12 V Constant) | A constant 12 V power source | Keeps the display powered whenever the vehicle's electrical system is live |
| Red (Remote Turn-On) | The same remote turn-on wire that powers your amplifiers | Turns the display on and off with the rest of your audio system |
| Ground | A clean chassis ground | The negative reference for the display |
The same three connections (Ground, Remote, and 12 V) are also available as pins on the rear of the unit, so a flush-mounted display can be wired in place after the cradle is installed.
- Connect the power cable to the rear of the WDD-LITE
- Route the wires to your power source, keeping them away from high-power speaker wiring where possible
- Match each wire to the correct connection: Yellow to 12 V constant, Red to remote turn-on, and the remaining wire to ground
- Secure the cable with zip ties or clips along its route to prevent rattling
When the remote turn-on line goes live, the display powers on automatically.
Run the 12 V Constant lead to your vehicle's battery or constant-power distribution block, and install an inline fuse (a small fuse such as 3 A is more than sufficient for the display's draw) on that lead as close to the battery as practical. This protects the wire run so a short cannot dump the battery or start a fire. The Remote Turn-On lead does not need its own fuse since it follows the amplifier remote circuit.
The WDD-LITE's power board includes reverse-polarity protection, resettable fusing, and automotive transient (load-dump) protection, so it is built to tolerate the noisy 12 V environment of a vehicle. These protections are a safety net, not a substitute for correct wiring: always confirm polarity before applying power.
Alternative Power: USB-C
The three-wire harness is the preferred way to power the WDD-LITE in a vehicle, because it ties the display's on and off behavior to your system's remote turn-on. For temporary or bench use, you can instead power the display from its USB-C port with a standard USB-C cable and a 5 V source, including a portable USB battery pack. This is convenient when you want to run the display outside the vehicle for a while, or to test pairing before final installation.
Use either the three-wire harness or USB-C, whichever suits the situation. For a permanent in-vehicle install, the harness is recommended so the display powers up and shuts down with the rest of your audio system.
Mounting
The WDD-LITE includes two mounting systems in the box. Choose whichever suits your dash and preferred viewing angle.
Option 1: Flush Mount
The flush-mount cradle lets the display sit nearly level with the surface it is mounted in, for the cleanest look in a dash, a flat panel, or any flat surface.
- Hold the cradle where you want the display and trace around its base, then cut an opening for it (in your dash, a flat piece of wood, or other paneling)
- Install the cradle into the opening
- Slide the WDD-LITE into the cradle, which gives the unit a few millimeters of lip to hook onto
- Secure the display with one of the provided screws so it cannot lift out
The result is a clean, nearly flush install. Because the rear power pins remain accessible, you can wire the display after the cradle is in place.
Option 2: Adjustable-Angle Base
The adjustable-angle base lets you tilt and rotate the display to almost any orientation, including angled, sideways, or upside down, so you can aim the screen wherever it reads best.
- Attach the angle base to the bottom of the WDD-LITE with one of the provided screws
- Set the display to the angle you want, then tighten to lock it at that position
- Fix the bottom of the base to your mounting surface with the provided side screws, or adhere it using the included double-sided tape, E6000, or another suitable adhesive
- Mount it wherever you would like the display
If you mount the display in portrait, flipped, or any rotation other than standard landscape, set the matching screen orientation in the menu so the image reads right-side up: long-press the screen, open Settings > Orientation, choose Landscape, Landscape Flipped, Portrait, or Portrait Flipped, and confirm. The display restarts to apply the new orientation. See Menus and Settings.
When using adhesive, clean and dry the surface first for the strongest bond, and let a glue such as E6000 cure fully before relying on it to hold the display.
Whichever option you choose, mount the display within easy reach for touch control, route and secure the power cable behind the panel, and verify the screen does not rattle once installed. For exact physical dimensions and the current mounting hardware, see the WDD-LITE product page.
First Power-On
- Power on the base station
- Power on the vehicle accessory circuit (or trigger the remote turn-on) so the WDD-LITE receives power
- The WDD-LITE powers up automatically
- On first boot, it shows a Getting Started wizard that walks you through pairing with your WVC base station
- See First Boot and Pairing for the complete setup process
Troubleshooting: If the first-boot wizard does not appear (the unit goes straight to a Connecting or main display screen), the WDD-LITE is already paired to a previous base station. Open the menu (long-press the screen), select Advanced > Forget Base (or Factory Reset), confirm, and the wizard will reappear on the next boot. This is the same procedure used when moving a WDD-LITE between vehicles.
Verifying the Installation
After pairing is complete, verify your installation:
- The main screen displays live data and the connection status reads Connected
- The voltage reading on the Volts tab matches your expected vehicle voltage
- Tapping a mode tab switches the view, and swiping left or right changes views
- Signal strength is reasonable (check in System Diagnostics)
If you experience intermittent disconnections after installation, check the Signal field in System Info and consider repositioning the WDD-LITE closer to the base station, or moving it away from metal panels and dense wiring.
