G10- Digital GPS Speedometer

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.

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 thing works pretty good. My only issue is how long it takes to actually recognize any satellites. Other than that tho, good product.

I have a Jeep Wrangler Rubicon with a small and nearly un-readable speedometer. I wanted something I could see and read that wouldn't break the bank. I ordered the Wiiyii HUD-G10 unit with some doubt that it would do what I need.Installiation was simple and the windshield mount was exactly what I needed. I drove around for about 20 minutes and observed that the unit is VERY readable in all light conditions. I was able to see and maintain numerous satellites and got a read-out of my speed and compass direction. I noticed the speed was about 2 MPH above my digital speedomemter reading. I followed the included instructions and adjusted the speed setting. I was able to sync my vehicle digital speed excatly with the Wiiyii speed display. I then corrected the time setting and was very pleased that I could easily see my speed, direction of travel and time. I then disconnected the unit and hoped it would retain my settings. After 10 minutes or so, I reconnected and was pleasantly surprised to see everything still set the way I wanted it.This was a VERY good purchase and low cost solution to have my speed and information where I could easily monitor it while driving. I would recommend this unit to someone that needs an inexpensive solution to a small speedomemter display.

Looks nice. Setup is ok but could be a bit better. Mine is off by 5mph. No matter what I do its consistently off.10/23/24 UPDATEThing has already completely stopped working. Changed cords, tried a phone charging brick, even cut the wire to hot wire it straight to my 12V....NOTHING!!!DONT WASTE YOUR MONEY!!!

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.

Pretty accurate for speed , easy to set up

I bought this to use on my golf cart and it works great. I used to mount my phone on the dash using a GPS app in order to see my speed, time, direction and trip mileage. But I was constantly pulling my phone off the mount to change songs or the volume via my BT speakers, answer calls, respond to texts, or whatever else most people do with their cell phones. This GPS speedometer has all the same features I used within the app on my phone. The screen is bright with great colors. I like that it's relatively the same size as my phone so I mount it in the same location in the same phone mount so nothing really changed from the norm. There are some settings that allow you view only what you want to on the screen making it very unique to your needs. I tested the gps speed against my phone app and it reads identical. Slightly slower during fast acceleration or deceleration, but I'm talking about a second or maybe tenths of a second compared to my phone app. Now my phone is where I need it and life is easier! It's funny, I still reach up to GPS unit to grab it when I hear a phone notification out if habit or I'm wanting to adjust the music volume since I used my phone in that location for years, hahah. Especially if I'm doing some booz-cruisin' 😆. I recommend this unit if your looking for a similar experience!
