    • 5 stars... and with a couple of reservations
First of all, this product is and does exactly what they claim it does. The 12" view display is VERY sharp and clear (with a couple of reservations I will address later), the wide angle lenses show everything and more, the GPS is accurate, and the rear-facing camera works very well, especially if you hook up the wire to the backup light so the unit displays the (adjustable) backup lines. Very useful in parking lots! The variety of settings and adjustments are impressive and useful. All-in-all, a really nice product. Now... here's some things I feel you should know.... First, I'm no expert in dashcams. I actually tried an inexpensive windshield mounted one, and it was okay, but I thought it used up too much windshield "square footage" and was a little distracting next to the rear view mirror - the only place I could fit it. Which led me to the units that fit on the existing rearview mirror. MUCH better for what I wanted. I originally just wanted the forward-looking camera and resulting recording, but the GPS was so easy to install, so I did that. Then, after some thought, I wanted to install the rear-looking camera. If you have a sedan with a trunk, this will be very easy. I don't have that. I have a 2009 Ford Escape, a smallish SUV style with a full hatchback as well as a window that opens. Lots of pivot points and moving parts. To get to the license plate light (the recommended routing and placement for the camera), I would have to nearly destroy the inside plastic panel covering the tailgate to route the wiring. And there was no good place inside the glass. So where? It ended up on the outside top driver's side corner of the hatch in line with the luggage rack frame - for a little protection. Not happy with that, but it works, and it's not the manufacturer's fault. Just beware if you have something other than a sedan. You may have to get creative. Another issue is nighttime rear view. The flare from the camera at night is fierce, and not at all useful for viewing out on the highway. In a lighted parking lot, it's fine. Great, even. Also, rain and snow. Just okay, but nothing unexpected or a design fault. It is what it is. Now, one other thing, and it's not a design fault, it's a part of what this device is... Think about it... You strap on this gadget that has a camera pointed straight forward onto your rear view mirror. It has a polished glass surface that is excellent for use as a rear view mirror all on it's own. And what's the first thing you do? You adjust the mirror, angling it down and towards you so you can center the reflection of the rear window in the mirror and see it by just glancing over, correct? And now that camera is pointed up and to the right, not straight ahead. It's a very wide angle lens, and this is not really a problem, but I fixed it by making a small wedge out of foam and inserted it between the unit and the mirror it's mounted on. Now the camera is pointed straight AND the reflection in the mirror is correct AND the rear-facing camera's image generally matches the real reflection. This is important on dark and cloudy days. I know this all sounds like problems and issues, but they are really not. I'm a fussbudget when it comes to stuff like this. This is a really good unit and does it all. I like it a lot. ... show more

    • So happy I can see out the back of my Jeep

So now that I’ve been living with this thing for a few weeks I feel like I can write an informed review. First the general stuff: I installed it in my 2016 JKU Wrangler entirely because of the crap rear visibility. That this is also a dash cam and gps speedo is just icing on the cake. Seriously, if you’re considering it, just do it. You will not be disappointed. The cameras themselves are great. Daytime and nighttime visibility is far superior to my old mirror. When the display is turned off, it still works pretty well as a mirror, too. I find that most of the time I can even focus on the reflection and the display separately, even when it’s powered on. Kind of like looking at one of those magic painting things if that makes any sense. My only tiny complaint is that the USBC power cable angles to the left and I didn’t like the look of that so I bought a separate USBC cable that angles toward the windshield instead. But that’s not nearly enough to knock off a star on such a wonderful product. Now for the Jeep specific stuff. 1. I watched some YouTube install videos that said the camera cable is slightly too short when installing this in a four door wrangler. This is true if you route the cable across the windshield, down the A pillar, and through the floor trim, as is the generally accepted way to go about it. I went across the windshield and followed the roll bar back instead. It’s a bit of work to run all that cable under the roll bar padding, but it’s totally worth it. No issues with cable length. Actually had about 3’ left over. 2. The GPS antenna cable is exactly (and I mean EXACTLY) long enough to go across the windshield, down the A pillar, and back to the center of the dash, where there is a perfectly sized flat bit (if yours doesn’t have the light sensor like mine doesn’t) right behind the dash tray to stick said antenna to. 3. Take the time to remove the top windshield trim and A pillar trim completely. This requires removing the sun visors, but it makes running the three cables much easier. Also consider putting a small notch in the windshield trim. Looks much nicer than having it bent out a bit. 4. I also recommend the windshield mount instead of strapping it to the existing mirror. Much better looking and it’s only another $20, so why not? It’s quite sturdy, too. 5. The backup camera mount didn’t look like it would reach high enough for where I wanted to put it, so I also grabbed an AMPS mount here on Amazon for that. With the extras I think I’m in for a total of $150ish and I think it’s probably the best upgrade I’ve done to this wrangler. Kinda wish I’d done this to my previous wranglers as well. ... show more

    • Not bad overall. But the glare is terrible.
Review Image by KuruCode KuruCode
Installed with the wolfbox fuse kit. Easy to install, rear camera varies on make model and how you want to do it. I think it works great for the black friday sale I got. The image is super clear front and back. At night or with sun behind you the back camera is pretty much bad but the front is still super clear. Without the bracket converter to completely replace your rear view it's kind of bulky. OEM came with garage door and auto dimming functions so it's ticker already. Replacing it completely though seems like I would lose the garage door buttons. The worst part however is the glare in the screen. The only thing that has really made me consider returning the product. Even with max brightness and in a vehicle with tinted glass the glare is extremely annoying and can make seeing what's on the screen very hard or impossible unless you move around. ... show more

    • Replaced mirror, backup camera, and dash cam
So cool! Great features and engineering. I got it to replace a backup camera, and it's good for that, but it's also a good dash cam and has a superior field of view as a rear view mirror. An extra benefit is that I finally have a compass due to the GPS module. I spent a few hours routing and rerouting the power and video cables, but I took my time and the results are really nice. Boot time is about 11 seconds. ... show more

    • Works well, easy install. Get the hardwire kit.
Works great, install was a breeze. Picture quality is awesome. I tucked the GPS under the ceiling, works just fine. I also did not hook up the red wire in the trunk to the reverse light, AND I got the hard wire kit. I love it. Mine stays on all the time for a full digital rear view. Windows extra dark tint, this solves the problem of reversing in low light. ... show more
