Head Up Display, Car HUD P8, OBDII & GPS Dual System, The 1st Model in The Market Can be Installed on A-Pillar Trim, Only Works on Most 2008+ Cars

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.

Works great with 2010 Jaguar XF-R X250 Supercharged V8. Shows engine coolant temp and battery voltage accurately. Compared values with a NIST traceable Fluke DMM. The voltage and coolant temp are parameters to keep your eyeballs on with these vehicles.

This was easy to install..which is good because the instructions lacked on that front. Works great for me. Information is easy to read and very revealing about my vehicle.

Does not work on a 2006 jeep wrangler. Just reads “this vehicle is incompatible with OBD2”. I have a Bluetooth ELM27 obd2 reader that works just fine, only got this so I wouldn’t have to deal with connecting my phone constantly to monitor things. Cheaply made and does not function the way you would expect. Installing would be easy, it does have a gps function but CarPlay does a better job of that.

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.

Works incredible. Every car should have one . Insane amount of info for the price

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

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.
