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

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 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!

The only thing he did was damage my car, now every now and then my car goes crazy because of this product, this thing is useless!

This is a pretty easy plug and play option for any vehicle, I have mine on my 24 Ford Maverick. Just needs a better Mounting system. Has important info that anyone would need to know about their vehicle like if you are towing. Also it does not get in the way because of its size. Anything with an adhesive will more than likely come undone like the bit of Velcro that is provided.

So starting off, all off the readings are vehicle dependant. some of the readings may show up in one vehicle and wont show in another, like rpm readings or fue readings. another issue i have is that it doesnt turn off even after vehicle is off and locked. you have to manually turn it on and off all the time. There is another quirk when it starts up wheere it displays "vehicle not compatible with obd2". you have turn on the device switch it to gps at start up ,turn it off again and select obd. if you dont mind all that well this is for you for the price.it didnt work well in one of my cars so i put it in my other car where it works just a tad bit better but not by much.

I was looking for the smallest HUD I could find that could give all the features of being plugged into OBD2 and this one fit the bill. I installed it in my 2013 Acura TL over a year ago now and it has performed flawlessly. Initially it read the mph a bit higher than I was actually going. I had to bump the adjustment value down a couple of points. I believe the default value was 107 and I set it to 105. It's perfect now but at speeds above 70 mph it reads two points higher. There is another option in the settings to fix this I believe but I didn't bother. I have no problem seeing the screen during the day and it automatically dims at night. I have my screen setup up to show mph, clock, rpm's and coolant temp. The clock is a 24hr format and cannot be set to a 12hr format which is a bit of a bummer.I've had zero issues in the year that I've owned this. It comes on when I turn the car on and shuts off when the car does. It has not caused any lights to come up on the dash or interfered with any of the car's functionality in any way. I hope in continues to works for years to come but if does die, I'd buy another right away.

Awesome quality product, worked just as described

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.
