OBD2 Gauge Display Car HUD Head Up Display,Speedometer for Car P8

I drive a 2018 subaru impreza hatchback. Was very easy to install, simply plug it in and stick it to your dash or windshield. Hardest part about installing it for me personally was finding a place where it would fit and had a flat surface to stick to. The shape of it is a little bit awkward and my A pillars weren’t quite wide enough to stick it to and not have it be kind of an eyesore but the underside of the top part of the dash where my clock is was a good spot for it. All of my stock gauges in my cluster work perfectly fine but seeing as it’s a base model impreza I only have my tach, odometer, fuel gauge and speedometer so I wanted something that could show me oil and coolant temperature at the very least and this display does a great job of that as well as a few other indications that I find convenient. I do wish it could display oil pressure but if something goes wrong with my oil pressure the idiot light on my dash will come on so it’s not the end of the world. I was skeptical about the displays functionality seeing a bunch of reviews saying the auto sleep doesn’t work consistently and all these other issues people have with it but I have not had a single issue with it. Others have said they set the auto sleep to when the battery reaches 13.6v or so but theres an option in the settings to set the auto sleep to “RPM” so that it turns off whenever the car isn’t running and it has consistently turned off automatically when I shut the engine down. Others have also had issues with an inaccurate speed indication on the display vs their own speedometer but since I first plugged it in it has been accurate within +/- 1mph and there is a setting to adjust speed compensation so the speed indication reads more accurately. Product is light and made of plastic so I wouldn’t imagine it’s terribly durable if it falls on the ground or is hit by something hard but seeing as it should just be stuck to the windshield or dashboard it should generally be out of harms way. There is a brightness setting that includes an “auto” option so that the light sensor on the back of the display can auto adjust based on conditions in the car and I haven’t had an issue with it being too bright at night. Overall I would honestly say it’s worth the price if you really care about being able to see oil/coolant temperature, battery voltage, intake pressure, MAF volume, fuel flow, and even boost for those with turbocharged engines, etc. And if you have a broken tach or speedometer or something that adds even more value.

I have an aftermarket tuned AMG Benz and use this exclusively for monitoring my boost. It's perfect for that, as it's small and you can mount it in multiple ways and it has settings to adapt the screen display for whatever orientation works best for you. Plenty of people skewered the reviews for reasons that aren't the fault of the device. The temps etc that it displays are simply whatever the OBD data stream tells it- that's it. The speed may be a few MPH different from your odometer, but that's the speed it's being given by the data stream- OR one can use the GPS to determine the speed more accurately. Speedometers in cars are often incorrect- as they aren't required to be, as they have up to 10% variability allowed. This actually has the potential to be more accurate if you adjust the offset to "correct" the data stream. It doesn't interpret data- it simply reports it. I've had it in my car for a year now and no issues at all. On rare occasion, I'll use it to check other measurements, but it's really only being used to show my boost. This is by far the best HUD I've tried, and I've tried many of them and quite a few hit the trash or got returned for being awful. If you have a very early OBD vehicle, you won't likely get ALL the data streams you want and it's not the tool's fault- it's your car. Some people are just unrealistic and don't know enough to know what's at fault. For a simple display that takes very little room- you can't beat it!

Overall a good device that is exactly what I wanted. Installation and mounting was very simple, I just need to route the OBDII wire a bit better on the A frame moulding. For the unobtrusive size, placement options, features, and price, I don’t think this HUD can really be beat. I don’t like to look down at the dash while driving at night because of how bright headlights are these days I find it difficult for my vision to adjust from checking my speed to focusing back on the road again. So I’ve been thinking about either buying a cheap phone and using that with the UBD fusion app to create a HUD that could reflect off my window, or building my own OBD dash/display with an esp32 type controller. Also thought of using an eink phone or display but refresh rates just aren’t there yet for consumer off the shelf products. So I went the slightly lazier route and just picked up this HUD, much better option for the present moment. The only knock on this device was that the included Velcro was not nearly up to the task to mount the device to my A-frame, so do yourself a doctor and buy some heavy duty Velcro strips to cut to size and use for mounting. Oh, and regardless of your locality settings the fuel per mile is locked in at km/l which isn’t helpful in the US where mi/g is the standard.

it has all the data pulling from the obd port but it only lasts 3 months. Doesn't have a solid warranty info, manufacturer refused to step in

So this seems like a really cool lil tool for older obd cars and it's very close in my opinion. Setup on my car was easy and had no issues connecting with obd. It's easy enough to flip through the menus and a small adjustment to the speedo in the settings and it is dead on with my cars speedo and GPS on my phone. Be a lil careful with leaving it plugged in. It has a power switch and I haven't had any issues just turning it off but some have said leaving it plugged in for long periods may still drain your battery. Best to just unplug it if you're not gunna drive the car for a few days. So now for my two big gripes after getting more into the unit. The first is the customization of what info you can display. You can only change the bottom most parts of information on each screen and it makes a lot of the screens less useful than they could be. I was most looking forward to the 6 unit display to easily show a number of parameters id want but since the top 4 parameters are locked im stuck with time running and distance traveled always being displayed. The second issue is the screen brightness. It's actually too bright in my case and while it's fine during the day at night it's blinding to have on the dash. It's supposed to have an auto adjustment but doesn't seem to change and manually lowering to its lowest setting is still too bright for my liking at night. Overall I'm a bit splitit does work and is an easy way to keep an eye on my water temps but it just could be better and ultimately left me a bit disappointed. I'll be looking for a revision or maybe a pro version with a lil more customization options down the road.

I've used a few of these type of HUD before, and a persistent problem I've had is that they won't shut off when you turn the car off. This drains the battery, which makes the whole thing not worth the effort. This HUD worked pretty darn good out of the box, and after a brief calibration, it was perfect for everything I wanted to do. I've mounted it on the dash above the steering wheel using some of the included Velcro, which sticks very well. To calibrate it, drive the car at a few different speeds and make a note of how far you are off between the actual speedometer and the HUD, then stop the car and adjust the speed parameter up or down depending on which way you were off. I've calibrated mine so that it's pretty accurate from about 15 to 70, which is most of the time you would be using. Definitely great value for the money. It's this, a backup camera, and Android Auto/Carplay for the big three of car upgrades.

It works on a 2010 Elantra. I have no temp gauge so that bothered me for the longest. I bought a cluster from another Elantra (2008, also manual transmission) and it didn’t work. The 2008 did have a temp gauge from factory, so I thought it would be plug and play. It definitely plugged in, but my tach didn’t work along with other things. Just putting that out there in case someone else ends up in the same situation I was in. This digital gauge works, and it works well for what it is and its size. But for 30 bucks, it’s overpriced for sure. Temu had this one for 10$ less but I figured the hell with it, just get it done and over with. I chose to mount in front of my oversized fuel gauge, being that it would only block two lights on the dash, the immobilizer light which I don’t have, and the engine temp idiot light which id no longer need 😂 so it worked out. Pictured below is a rough draft of where it’ll be, once I take the frame of the cluster out and do a bit of wire tucking

Like others have mentioned, it will not turn itself off with any kind of predictability. I have followed the instructions and set the sleep voltage for 13.6v, the device is reading the battery at 13.4v but never shuts off. The sleep timer is set for 300 seconds, after 5 minutes it doesn't shut off. Sometimes it will, most of the time it wont. The boost gauge is in bar. This should be able to be changed to PSI as nobody in the US is using bar for boost pressure. It would be nice if you could choose the parameters that are shown on the screen, or at least have SOME customization of data on the screen. I'll give it 2 stars because it does work, at least in my vehicle.

I'm driving somebody else's car at the moment, and because I sit a high in the seat being very tall, I find it hard to see this speedometer especially if it's very bright. . This has a very small rectangular screen and it sits quite obtrusively on the dash mat in front of me. It has a lot of options that can be displayed, but all I wanted was the speed, so I just left it with that, and it's perfect. It's a paperwhite display which I like. Very much fit for purpose. .

軽自動車のOBD接続でちゃんと稼働し、車のシステムに対して変な影響もないようで一安心。表示数値は正しいようだ。付属の説明書は非常に小さい印刷文字の機械翻訳らしい日本語だけなのに対して、本体の表示は中国or台湾or英語だけで一致せず分かりにくかった。本体形状が、ピラー取り付けも考慮したものなのかもしれないが、どうも異形の感じでイマイチで置きにくいし収まりも悪い。

Love it! Excellent display that looks like factory installed displays. I am very picky about products not meeting my standards, this one I love! Installed in my F350 Ford as the truck is from Texas so MPH speedo, here in Canada we use KM so this works perfectly.

It met my expectations and requirements

ディスプレイの６種類表示は、上と真ん中の４種類は固定、下の２種類しか選択できないので、マルチ表示ができないに等しいです。 水温計の値は、走った後10分以上アイドリングするも、92度で止まったままなので、怪しい感じです。
