wiiyii Digital GPS Speedometer, HUD Head Up Display for Car, Upgraded 5.5" large-screen, Suitable for All Vehicles

I had bought other types of HUD of similar build and they were never accurate. With this one I was able to correct the speed reading to match exactly as my car’s speedometer. The install was easy and it is working perfectly. The size is small enough to place out of direct view but perfect for its HUD function. I noticed the piece responds to different outside brightness levels very fast and accurately. It looks like this purchase was the correct one. I definitely recommend

Five star review. These are a nifty gadjet for vehicles without a HUD. Green is the color to go with especially at night and with the suction cup mount and large screen it can be fixed according to your specific vehicle and hooked up very easily. Five minutes to install it is a cinch. Has many modes with information, remember safety first and never get distracted while driving. The current speed and info is astonishingly accurate, we were very very surprised it actually worked really smoothly. So after a couple of test runs in normal city driving with the speed, direction, and number of satellites mode the acceleration of the vehicle and of course the screen displaying info was just a hair behind and would be accurate to the point. When you stay at 30 MPH it catches up within two seconds and decelerations were perfect too. The direction matched the cars built in compass and who knows how many satellites are actually up there but it was very nice to see an inexpensive product that actually works. It's a USB plug in too, not a 12 volt so even better yet. After normal daily commutes for a week it continues to surprise me and am so happy it works accurately. Update- eight months later the HUD is in perfect shape no problems at all and was a great buy, highly recommended product.

Nice unit that fits well on my dashboard right above my original speedometer. Unfortunately, the original has become more of a suggestion than an accurate measurement so I needed a workable solution. Installation is fairly straight forward with a pretty good suction cup base. I chose to use a strip of velcro rather than the included double sided tape. It has several selectable options and although the instructions are a little cryptic, it isn't too difficult to figure out. It has a clock that is helpful and a trip meter that resets every time you start the vehicle. Doesn't store trip info but for my purposes that doesn't matter. The speedometer section can be either a graph or digital but not both. I like the digital. Large numbers and easy to read. Only two inconveniences is the speed can be a bit jumpy and difficult to hold exactly. But I've only tried it with the digital setting and it isn't a deal breaker. If sunlight hits the face of it you can't see it. But, that's a problem with most electronic screen devices anyway and doesn't happen very often. Curious to see how it holds up in direct sunlight as it is under the windshield and summer is coming.

I am happy with the quality of this little guy, I had an old car with a speed sensor that constantly failed and this removed the guesswork in how fast I was going. When I first tested it in a different car for accuracy, the speed with accurate within 1mph. There is a small delay on startup while the device aquires GPS signal, but that's to be expected with any device like this. I also enjoyed the other functions and customizability of it. Overall this is easily worth the money.

This unit is ABSOLUTE JUNK. It’s literally impossible to follow the so called instructions. The provided sheet tells of all of the features but never details how to get there. I spent over 2 hours trying to change it from kmh to mph. Maybe it was defective but I doubt it!

I installed this in a car that I do not have a decent speedometer in. Plus I liked the idea of a clock in the same unit. But with that said it does seem to have a problem searching and finding a satellite signal. Sometimes the clock doesn't show a correct time (only a random minute reading) and the speedometer reading is absent sometimes as well or simply independent of the no correct time reading. And no, it is not a setting issue. I have tried all settings that would effect that. Also I have moved the unit to the windshield to be sure it can get the best chance of receiving a signal-- still the same problem. And while the no correct time thing is a non-critical issue, the lack of a speedometer is the main issue-- since it is exactly what I wanted to gain by having this unit in the car. Having it work spuratically is a real problem. On a related point, the cable at the end that plugs into the unit is VERY cheap and fragile. Be careful with it as it can bend and become unusable fairly easily. Mine bent and the unit went blank. Fortunately I was able to bend it back and it came back on. But still, I'm trying not to even disturb it any longer for fear of a broken cable that would render the unit unusable. When it works it seems accurate and is great -- but sorry, only three stars for the quality and the non connectivity to the satellite issues.

Perfect choice as my car speedo does not work at all and this plugs in easy and works with GPS speedo

Este dispositivo me gustó porque una de sus características principales es el velocímetro digital vía satélite, además me caía de perlas porque el de mi camioneta, una Jeep Liberty no le servía, todas las demás prestaciones que incluye el dispositivo le funcionan correctamente bien como es el GPS, reloj, altitud, etc. Lo recomiendo ampliamente 🤗

Love it. Very sturdy and well made. Precise as well. I use it on my motorcycle and works flawlessly. Thumbs up.

I would have given 5 stars had it not been for the supplied cable. It should have come with a 90-degree USB-C connector to the unit. The supplied cable (whilst the length was sufficient) prevents the unit from being placed close to the windscreen. Easy fix, just get a 90-degree adaptor. Why it earned 4 Stars: 1. The unit adjusts the brightness in seconds when going through a tunnel. Importantly, the unit does not dazzle the user at night. 2. It is responsive to the change in speed, but it does not display speed below 4 kph. 3. Quick enough to connect to the satellites. 4. There is a function to calibrate the displayed speed, so it is flexible; you can set it to match the speedometer reading or as a GPS reading.

Nice gadget, bright, accurate and retains its memory after being turned off. Only thing the setting up is non- intuitive but possible with the instructions. Not sure where they will be too next time I need them.
