AZIJYV Windshield Speedometer Projector, Digital Speedometer for Car GPS Speedometer with Speed, Overspeed, Heads Up Display for Cars Suitable for All Vehicles

The AZIJYV Windshield Speedometer Projector turned out to be a surprisingly handy little upgrade. Setup was quick — plug it in, let it lock onto GPS, and the numbers pop right up on the windshield. The display is bright enough to see in full daylight, but not blinding at night. The speed readout stays accurate, even on backroads where phone apps sometimes lag. I like that it shows your speed without needing any wiring into the car’s system. The projection is crisp, the unit stays put on the dash, and it doesn’t clutter up the windshield. It’s especially useful on long rides where you want to keep your eyes forward instead of glancing down at the dashboard.

This is a good simple HUD unit that can display time, speed and compass direction using GPS. You just put it on your dashboard and let it reflect off the windshield. There is a film you can attach to the glass to make the reflection clearer. There are different display modes, letting you choose which elements are displayed. I've read that some people say that it is inaccurate. For me, the default settings made it display speed that was 10mph too fast past 50mph. I was able to adjust it so that it was within 1 or 2 mph from 0 to 65mph. Press and hold M to enter the menu. The first screen will show an adjustment value (I think default is 107 or something like that). Lower it to 102. Press and Hold M again to save and exit. That worked for me. The instructions are not very clear on that, but basically if it is showing too fast a speed compared to your speedometer, adjust that value downwards. If it is showing too low a speed, adjust it upwards. Limitations: 1. It uses GPS, so it takes a moment to find the signal when you start the car. 2. It uses GPS, so when you lose the signal (like in an underground parking) it will show 0mph. 3. In bright sunlight, its projection can get washed out. 4. If you wear polarized sunglasses, it may filter out the display as well. All in all, for the price, it's a good unit if you don't need anything fancy.

Great when it works. But stops working on hot days.

Get what you pay for. Its off 5mph consistently. The refldctive piece that went on the windshield almost blinded me itself

This was easy to install and I bought a hardwire kit so I could tap my fuse box and hide the install. Looks great, used 1/4 inch black plastic auto wire conduit (about 4 inches worth) to hide and protect the exposed wire on the dash area from direct sunlight damage and make it look clean. The unit comes on when I turn on my car and gets a satellite signal within 10 seconds so by the time I back out of my garage and drive to the end of my street it starts working. I had to follow the directions to fix the speed calibration and it is dead on the correct speed now. I have had it installed for about a month now and it is getting very hot here in the Dallas TX summer sun. It gets covered by my sun shade while it is parked at work. Not sure if this is due to heat but my wife and I took a drive out into the country a few days after I installed it. It did well for the first part of the 3 hour round trip but on the way back, it locked up on 0 mph and 7:00 and that did not change until I restarted the car after we had been back for about an hour. It did not do that again until yesterday when I was at lunch. I got back from lunch, turned the car off, went inside for about 2 hours then it did fine on the ride home, no issues. Not sure if this is heat related. I am able to see it without using the provided reflective static window cling used to reflect the light better during bright day light but I may try the cling soon to see if it helps during the day. Also, the unit has an auto dim for night use that helps a lot and looks nice. It looks the best at night or sun rise, sun set. The numbers for MPH are big and easy to see even without my glasses. I can also read the smaller clock without glasses. Its hard to see the compass and the timer numbers. Looks really good with my glasses on, very clear and looks very clean. Unit is black and very small and blends into my black dash. For the price its a nice little gadget but if I were to buy another I would get one that attaches to my OBD port and use the cars computer data to get speed and other info but also has a GPS to give a compass. Maybe $10 more. Nice little gadget. Easy way to make an older car feel a little more up to date and a newer base trim level car feel a little more luxury.

This unit is pretty much a plug and play type of accessory, and once adjusted is extremely accurate and enhances every drive. Initially the HUD was off between one and a half and two miles an hour as compared to my speedometer; with my speedo reading 50 mph the unit was showing 52 mph. After looking at the almost incomprehensible 'instructions' I was ready to leave it that way. Every BMW I've owned has been similarly optimistic, and you get used to it. But it was a rare top down winter day in Michigan - 66 degrees in February - and I wasn't in any rush to get home and park the car. So I drove a bit, stopped and made an adjustment, then repeated that two more times. In less than 10 minutes my speedometer and the HUD were dead on. I chose not to utilize the piece of plastic film provided with the HUD to increase the contrast of the readout, because I can see the reflection in my windshield fine without it, though it is less obvious in the daylight than at night as seen in my video. While the factory HUD in previous vehicles was more or less directly in front of the driver, I chose to locate this one almost in the center so my dashcam picks it up without any distortion, but that's a personal choice. If you appreciate having a simple HUD, this is an excellent choice.

I bought the AZIJYV Windshield GPS Speedometer because I wanted to feel like a fighter pilot while driving my 2012 Honda Civic. Who doesn’t want their speed projected onto the windshield like they're about to jump to hyperspace on the way to Target? Out of the box, it looked sleek. It had that futuristic glow. I felt cooler just plugging it in. “This,” I thought, “is going to change the game.” And it did… if the game was called Guess That Speed! Let me be clear: this thing does display numbers. They just may or may not be the speed you’re actually going. Sometimes it's bang on—100% accurate, GPS-laser-guided precision. Other times, it’s off by 5, 10, or... what I can only describe as "vibes." One time I was parked and it proudly declared I was doing 8 mph. Maybe emotionally, yes. But physically? Not so much. It’s like this speedometer went to a motivational seminar and came out with the attitude: “Accuracy is overrated. Believe in yourself!” Want to know if you’re speeding? Maybe it’ll tell you! Maybe it won’t! It keeps things spicy. Think of it less like a tool and more like a roulette wheel with numbers that occasionally match your car’s speed. But hey, when it does work, it looks super cool. That glowing number floating on the windshield really sells the illusion that I know what I’m doing with my life. It’s a shame it sometimes thinks I’m doing 52 on a residential street... when I’m sitting at a red light. Two stars for the aesthetic and the random moments of functionality. Great if you like to live on the edge, question reality, and enjoy guessing games while driving.

I have an older truck a 2012 Dodge ram and it has the analog speedometer, etc. having this on my windshield makes it so convenient and so easy and not having to look down I can look right through the window and see what speed I’m going very handy very safe

Trabaja bien, me gusto, me preocupa un poco que se calienta , entiendo por la energía que consume pero más por el sol que recibe, pero trabaja bien. Mi vehiculo no tiene toma corriente que se apague al apagar el switch de encendido, así que tendre que ver a mi Electrico para hacer una adaptación de lo contrario se queda encendido siempre

Product as described easy install

Very good

Bom dia eu gostaria de reclamar que o meu aparelho veio com defeito eu ligo ele no carro eu tenho um fox 2019 eu ligo ele tanto no USB quanto naquele carregador de celular eu a bússola o GPS fica piscando o tempo todo mesmo colocando do lado de fora do veículo não consegue funcionar desde quando eu recebi o pedido já tem quatro dias eu rodando com o carro e esse aparelho não funciona só fica piscando

This thing punches far above its weight for the money. I bought it because I was curious about installing an HUD in my FJ, but didn’t want to spend a pile of money. And if that’s what you’re looking to do, then this is the unit for you. This thing works incredibly well, and far exceeds my expectations. It does exactly 100% what is described, and it does it well, much better than the $35 price tag would have you believe. The HUD image can be clearly seen when driving into direct sunlight, it does not wash out. The speed can be adjusted to exactly match your speedometer, I set mine to “100” from the factory setting of “107” and it’s dead-nuts accurate. The over speed alarm triggers on at whatever setting you set it to and it works as advertised. Like I said, my unit works 100% as advertised, now I can’t speak on longevity as I just finished installing it, but I can say that I don’t really want to live without it after using it.
