Heads up Display for Cars Speedometer for Car, HUD Digital Speedometer for Car with Speed Alarm, Fatigue Driving Reminder, Upgraded 5.5" large-screen, Heads up Display 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.

Nice unit, worked right out of the box. Very accurate up to 45mph but the faster you go from there, it starts getting off. Using two different GPS units to check accuracy, at 55 it reads 57. At 60, it reads 63.

Works great to show speed and other handy metrics on my EZGO Express S4. I didn't realize that I would lose the OEM speedometer when I replaced lead acid with lithium. Quick hunt for solution, I found this and now I don't miss the OEM speedometer at all - apparently the stock speed number is notoriously inaccurate, and I appreciate the odo and other information on this. Fits great in cubby over the steering wheel. I wish the odometer kept decimals after 10 miles, but small gripe. At 10 miles, it only increments by full mile - 10, 11, 12, etc. 10 miles and below, it increments in 1/10ths of a mile.

Driving at 65 mph it shows 95 mph, drive at 30 unit shows 58 mph Even though it showed 13 satellites of strength. Changing from mph to kph made no difference, it was also way over. Altitude, direction, coordinates all were accurate. Screen visibility and brightness is outstanding. Just didn’t provide me with what I purchased it for! Looked on the internet for information to possibly recalibrate the mph but can’t find any information on how to do so. So that doesn’t appear to be possible.

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.

Bought this because the instrument cluster on my husband's truck doesn't work. This has been super helpful as he can see how fast he is going. We even tested the accuracy of it with Google Maps speed and it was spot on. I love that it has so many functions and it is easy to see at night without being too bright.

Looks good and not too big or too small. Contrast is great during the day and not too bright at night. Bought it because my factory speedometer is incorrect because of its age. The compass and speed warning are just added bonuses. Would recommend for someone in the same situation.

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.

Large screen is bright and easy to read, even in sunlight. Simple plug-and-play GPS speedometer that works well with any vehicle.

This product works well. Ease of use. Pleased with purchase.
