Real Performance, Factory Look
The Uniden R4W Extreme Radar Detector already delivers top-tier performance, featuring long-range detection, precision alerts, and wireless control through the R/TACH App.
Now, with the Uniden Hardwire Kit, you can take it a step further — achieving a clean, OEM-style install that keeps your dash clutter-free and your setup truly professional.
In our latest YouTube tutorial, creator KrisB walks through the entire process — from cable routing to ignition power connection — proving that a factory-quality install doesn’t require a shop visit.
Why Hardwire Your R4W
Plug-and-play works fine, but a hardwire installation:
-
Eliminates visible cords for a clean, integrated aesthetic.
-
Powers on with ignition, so your radar detector is always ready.
-
Frees up your 12V outlet for other devices.
-
Enhances reliability by providing a steady power source.
It’s the preferred method for drivers who care about both performance and presentation.
Step-by-Step Installation Overview
1. Plan Your Mounting Spot
For optimal detection, mount the R4W high and centered under the rear-view mirror. This ensures maximum range and minimal obstruction to the windshield.
2. Route Your Cable Smartly
Tuck the wire neatly under the headliner, pillar, and dash panels. KrisB recommends leaving about 4–5 inches of slack at the detector end for easy adjustment.
3. Install the Control Module
Mount the control module where it’s easy to reach — for example, atop the steering column. The included mute button and LED indicator integrate seamlessly for fast access.
4. Power & Ground Connection
Secure the ground behind a 10mm bolt, then use the provided TTAP connector to tie into an ignition source wire. This allows the R4W to start up automatically with your vehicle.
5. Test Before Reassembly
Connect your radar detector, turn on the ignition, and confirm the power sequence. Once verified, reinstall panels and finalize the radar’s placement.
Pro Tip: Pair with the R/TACH™ App
Once your setup is complete, connect the R4W via Wi-Fi or Bluetooth using the R/TACH™ App.
You can update firmware, tag frequent radar zones, and customize your alerts — all from your smartphone.
This integration turns your R4W into an innovative, adaptive driving tool that evolves with every drive.
