    • 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

    • Just buy it. You need it! It pays for itself I promise!
SAVED me several times. No, I’m not supposed to have it. No, I’m not supposed to speed. But this handy little detector works from even miles away! I have hours of highway time and this little nugget lets me know of any speed radars hidden or out in the open WAY in advance. Worth every penny!

    • Good Hardwire Kit for your Uniden Radar Detector

I wanted a hardwire kit for my Uniden R3 because I was tired of having the power plug cord dangling from the windshield and getting in the way. (Why else, right?) I decided to go with the Uniden Kit because it has a silence button making it convenient to mute the unit when necessary. Installation is relatively easy especially if you have a fuse box near the driverside dashboard by the A Pillar, like on my Sierra. I just slid the flat telephone wire type cord under the ceiling and door trim using a plastic panel tool to the fuse box. If you purchase a tap wire setup for your type of fuse you just find a switched circuit fuse, pull it, plug in the tap, replace the fuse in the bottom slot of the tap, and your radar detector fuse in the top slot of the tap, and connect it to the red wire on the kit. Connect the black wire to any good ground screw, bolt or nut and you're done. I used the velcro that came with the unit and located the button box on the side of the console by the leg well where it is easy to reach and discrete. The unit works well and I am happy with the purchase and would recommend it to a friend. ... show more

    • Love it! Buy Fuse Tap kit at the same time! Trust 🙏
Worked perfectly! Just what I needed. I even hid the button in the dash panal for a clean integration You must get a Fuse Tap kit when you buy this. It'll make your life 10000x easier. Just plug it into the same slot as the 12v cigarette power.

    • 2nd best option
The kit is exactly what you need if you don't have a powered rear view mirror OR if you just want a discreet mute button location. Just keep in mind that you can program your Uniden R7 in a way that makes the mute button nearly irrelevant. Plenty of nerdy websites out there to help you dial it in so it's dead quiet until a real threat is known. I used this wiring kit in my truck because it does not have a powered mirror but my Honda does. Hands down, the powered mirror is the fastest, easiest stealth install. However, this is a good second option. ... show more

    • Great cord
I have used many kits to hard wire my radar detector. The weakest point in all the ones I have used, is the sturdiness of the cord and the modular plug. I have had a few instances where the radar mount has dislodged from the windshield and when this does, the wire is ripped from the plug. I didn’t really need the cigarette lighter adapter or the remote mute function. The suction mount is the same as the original and works better than the regular flimsy ones, however it’s not full proof. I just wanted the cable for how it is constructed to the modular plug. It has fallen once since install with no issues at all. Pricy for just the cable but very happy with the construction. ... show more

    • Great addition to my Uniden Detector
It is very inconvenient to reach up to the windshield while driving to push the mute button on your detector. This solves that issue with the ability to mount it at a place convenient for you. The LED light illuminates to confirm operation and detection and the mute button silences the alert just as the button on the detector does. It worked perfectly for my application and I would call it a must have accessory. ... show more
