    • Perfect Add-On for Your Detector!!
This hardwire kit is a solid upgrade. Install was straightforward, and once it’s in, everything looks cleaner, no more cords hanging around. The mute/mark button is super convenient, and the LED alerts are clear without being distracting. Power is consistent and reliable, and it integrates perfectly with the detector. It just works, no issues, no fuss. If you want a cleaner setup with added control, this is 100% worth it. ... show more

    • Installed in 2017 F150 for a Uniden R3
Bought this for my Uniden R3. Easy install to my fuse panel. I ran wire up the A-pillar and along top tucked into the headliner. I mounted the R3 on top of my rear view mirror. That's where the wire comes out and plugs into the R3. I picked a fuse that only has power when I turn my F150 on. So it has no power when the trk is off. I bought the kit back in 2024 but barely installed it 2 wks ago. Works great so far. You can even use the mute button to change the brightness too. ... show more

    • Works With My New R7 Radar Detector
I spent a little time and effort hiding wires and making good connections inside the dash, then mounted the little box in a discrete spot with the double-sided tape and no wires showing. The kit has a fuse in the power lead in case I made a mistake or something gets damaged. I'd previously added a tap for accessory wires connected to the power outlet in the dash, but the much smaller wire in the kit needs an appropriately-sized fuse to protect it. The cable for the detector is easily long enough to reach across to route up inside the A-pillar trim and access to the center over the mirror if needed. My nothing-showing stealth dash mount has most of that wire coiled up safely inside the dash itself. It's there ready should I change my mind. The good news -- It works as expected. There's a power LED, plus an activity LED indicator. I have yet to try the 'mute' button, since I'm going through the initial steps of driving around and letting the R7 learn and memorize the local radar speed signs. Even with the latest version of Uniden's location database, there are still some local sources that are getting discovered and memorized. Bottom line is that all seems to be working the way it's intended. The package comes with a pad of 3M double-side foam tape for mounting. My long-term success with using it to hold things in a hot (or seriously cold) car interior is mixed at best, So far so god in the first few weeks of fall weather. The little box doesn't readily split open, so there are limited options for a more secure mounting method. I have the little wire bundle passing through a not-quite-large enough relief in a trim panel, so it's pinched tightly but not enough to damage the wires. That's carrying most of the strain, so the tape just needs to support it enough to keep it from rotating. FWIW, I'm not at all afraid of DIY projects, including fabricating my own custom gadgets. That said, I just couldn't justify gathering the internal parts and pieces needed to build one of these custom for the car. Rather, this one fits with no modification to the car itself, so it will come out if/when needed leaving no evidence it was ever installed. For those reasons, this is a very good value for me. ... show more

    • Hardwiring looks best!
Its my opinion that hardwiring and attaching the radar detector from the rearview mirror looks best. Its a much cleaner look. Plus, mounting the remote mute button in a convenient place is also nice. I had my local stereo shop do the installation because I didn't want to deal with the door pins on my new Porsche. Of course the detector turns on and off with the vehicle and everything looks good and works well! ... show more

    • No more cords hanging from the window.
Just what I wanted. Fairly easy install. I added a fuse tap, instead of using the included wiretap. Works as advertised on my Uniden R4. So far so good.

    • Easy to install - makes for far better safety while driving.
This was easy to install and meets a really good purpose. It allows you to mark and mute false positives for your Uniden detector. I highly recommend this so you keep your eyes on the road at all time rather than looking over at the detector and trying to find the mute button.
