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 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!

i wanted an oil temp gauge that my base mustang lacks. this not only reads that info for me but it also works as a mini HUD that reads any info you want. i have mine to read speed ,RPMs, and oil temp. love it thus far. Definitely recommend.

I put it on my Lexus 300H F-sport (hybrid) and there were 2 issues, for some reason the hybrid mode did not work so when the voltage did drop (engine not running) it did turn off. Second when used in GPS mode then one time it did drain the 12 volt battery in 3 days. It did not destroy the battery but I will need to buy a new one before the winter or keep the charger always on when in the garage. One thing the on and off button on the hud is really cheapis and at times does not give full contact, once I thought something was wrong cos the voltage was to lo but after turning on and off on the button the voltage numbers were correct. Would not recommend cos of these 2 flaws.

Works for what I wanted.... a speedometer and a compass so I know what direction I'm moving. It's small and looks nice on the side of my car. 2 problems: the adhesive fails when I park outside, perhaps from the sun. I stuck it back on but I'll probably have to buy a new adjesive. The 2nd problem is the compass takes a few minutes of driving before it kicks in. Wish it was a bit faster. But overall a good purchase.

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.

This is a great little info device to add if, for example you need a temp gauge that many cars seem to be lacking these days. It's small and can stick on your door post or up on the dash. I actually look at the speedometer on that face more then my actual one. I seems pretty accurate, I did not have to make any adjustments. Overall I like it. I did have trouble sticking it to the door frame. It kept falling down with the velcro tabs. I wound up using Loctite Fun-Tak mounting tabs that were like putty and that finally did the trick. Overall I like it and glad I have it.

It's amazing how well this product works. It does not work with the vehicle that it's placed in, but works for the satellite amazing. Would buy again and recommend this.
