I picked this one because you don't have to have all the extra garbage on your windshield. All I wanted was the speedometer. Simpler looks more stock anyway. I ran only the speedometer the first few months, only recently did I turn on the RPM line (pictured). I like having that option. I can add more too if I wanted, but overall, HUDs look better when they're simpler. If I want to know more about my car, I'll use my dashboard or bluetooth OBD reader.Instructions were simple, and in english. Not sure why so many are having issues with this step.Picture looks a little blurry but it actually looks better than that. On the brightest days around noonish, it is a little harder to see, but still visible. This can be alleviated by using the included darkened transparent film. After a weeks, I put the film on to try it out, but in the end, I removed it. I prefer the look of my windshield without the square on it and I really didn't need it anyway. At night, it's very bright.I took one star away because of the "auto" setting for brightness. I mean, it's the only real option unless you want to change it manually all the time. I feel the brightness should have several levels of Auto. At noon-time, at it's highest brightness, I can see it, but I feel like it should do better to be more usable in that scenario. On the other hand, at night, it's brighter than it needs to be. Brightness settings should not be 1, 2, 3, or "Auto." It should be Auto 1, Auto 2, or Auto 3, which each being brightest for daytime (because it'll never be too bright with the sun out), but a dimmer night setting. Like each Auto 1, Auto 2, etc could be a differently level of dimmness at night.That's a problem I find with most chinese electronics, not quite bright enough during the day, but too dang bright at night as if they're compensating at night for what they can't do during the day.Overall, I do recommend this, despite my one complaint. My complaint is common among all HUDs so if you had to choose one, pick this one.You will have to fiddle with the settings to get it calibrated to your vehicles speedometer but it's not hard, you just gotta read the instructions.Most of the bad reviews on here are because no one wants to read instructions. They plug it up and then complain.

Loved the HUD. This is the closest to OEM that you’re going to see. I read a lot of the reviews stating that they had to calibrate the device after plugging it in. I can’t say that I had to do anything. I used the OBD2 port to wire the device and ran the wire through the A pillar and down the door frame and installation took all of 3-5 minutes. The trick is to place the device around until you get the desired projection, mark it and then stick with the given sticky pad. It hasn’t moved, and I even have it placed in such a manner that it’s near impossible for myself or the passenger to see that there’s even a device there. Everyone that’s seen it so far has asked me if the car came with it. Read the instructions, and I can’t stress that enough. If you just plug this in with the USB cable, you’re going to have a hard time calibrating this to read accurate speeds. As for the display itself, I think less is always more. You aren’t going to find an after party HUD that looks like something built with the vehicle due to the messiness of information and lack of it being built into the dash panel. This is great. Reads speed, and even shows a freakishly accurate rev counter. Try it out, you won’t be disappointed.

I bought this because my friend had one, and it’s practical for a manual vehicle. The first drive it worked ok, the RPM gauge on the HUD were less then accurate. Not a big deal. On the second day it stopped reading the car data and would not show MPH, or RPM. I unplugged it and plugged it back in and it gave me 4 engine codes. All electrical codes. If you have a car that’s 2010 or more up to date. DO NOT BUY!!

It does the job pretty well I am happy with it. I can see it on the screen in the dark and in daylight with the sun out. I was able to mostly tuck the wires into the side so it's not very visible following along the left side of my dash down by the windshield then up to the side of it and down to the little plug-in.the only drawback was the instructions were not very clear and the English translation was a bit tricky to decipher. you have to push a few buttons to get to a certain mode or whatever the you want it to show which for me was just miles per hour and I ended up having to just mess with it a bunch in till finally it showed me what I wanted and had to convert it to mph. Once I got it there I have no other reason to push the buttons though so I stuck it on the dash and it's awesome. It turns itself off after the car turns off which is nice too. I have my plug into the OBD2 reader you can do this through the other like cigarette lighter thing you know whatever but this is much cleaner and doesn't stick out or have cords and things you got to flip

It really does work well, take a little to set up, however it caused my vehicle tracker connected to the same old to malfunction, in go’s mode it is slow to keep up with changes in speed.

Very simple to connect. The display is pretty easy to read in most conditions - a bit too bright for night driving sometimes. Had to adjust the speed ratio to get it to match the car but no big drama.Speed display tends to lag a bit but is only annoying in city traffic and is very usable on the highway.

Initially, I was not really impressed with this and I was contemplating requesting a RETURN and Refund.The main issue was that unit ships in a state which will NOT auto power down! The base unit itself would remain lit and the backlighting of my 2018 Sport Night Edition, 6-gauge dash cluster with 7” LCD central info screen would stay ON !!... This was indefinite and would of course be a Battery KILLER!The supplied “leaflet” has poorly worded instructions in a barely readable tiny type font! and using the all-in-one single button/Jog dial for altering the unit's settings feels counter intuitive. After a lengthy and rather frustrating trial and error set-up period I was able to FINALLY get it right. This will (for RAM Classic owners) require you to get to menu item #9 and set voltage to 13.2 volts) Once you have managed to navigate this convoluted process your unit will Auto off when your dash cluster cycles through the vehicle shutdown process.Ok, after that long bit of frustration aside..The “POSITIVES”...- Did not cause any info anomalies on the Ram Classic dash cluster and did not throw any OBD error codes!- Base Unit is fairly unobtrusive and neatly nestles onto the first ridge in the upper dash of the Ram “Classic” just behind where the VIN plate is located. For me, this location also provided what I felt was the optimal projected image unto the windshield. This location also allows for the complete concealment of the connected cabling.- Speed and Info appears to display accurately which should be expected since its just pulling OBD info.- Projected image seems bright enough in sunlight and auto adjusts as conditions darken.- For the money (once the set-up is sorted out) this is a decent, functioning useful piece of gear.The “NEGATIVES”...- There is a slight “double-image” in the glass. No amount of repositioning of the base unit will eliminate this as its an issue of simple physics! (Ie: Windshield safety glass construction) However, I have not made use of the supplied screen reflector yet. I am trying to avoid affixing anything to my glass at this point.- TERRIBLE instructions! A little bit more detail may have taken 1 hour of frustration out of the process. I was almost at the point of wanting to call Amazon to request a refund!In the end, this was almost exactly what I was hoping for! I had been used to having a HUD in some of my prior vehicles and I missed having one. This unit allows me to leave my LCD cluster in the “Fuel Eco.” Screen or “Tire Pressure” Screen while projecting my Speed into the windshield glass. I set the unit to be as clean as possible by showing SPEED ONLY.. (No bar graph or useless dots) I have to say that this thing is fantastic during night driving.After getting the unit to now properly power down I am going to up my rating to 4* where it would have been 1* (ZERO) if I had ended up returning it.At some point I may try using the supplied transparent reflector screen to see if it cleans up the image a bit and will report back if I think it affects my rating. For now, the image is acceptable to me.Sorry for the LONG RAMBLE, but I hope it will help 2013-2019 RAM "Classic" owners to get the most out of this product.One final note: I did not attempt to use this in the USB powered mode at all and can offer zero input as to trying to use this in that way. As far as I am concerned, the whole point of having one of these is that it can function and gets its required power simply by connecting directly to the OBD port.

Easy install into the OBDII connector. Very bright for evening and night drives. Did not expect much during mid day sunlight but still slightly visible. Very well built.
