    • 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

    • 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

    • Works as it should
Works great for my truck now i can easily mute alerts without having to reach my arm all the way to the rear view mirror. Plenty of wire to make it work in your vehicle.

    • 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
