d.Be aware of your car the year of manufacture,which earlier than 2003 year may not available for this HUD.

There was a problem filtering reviews right now. Please try again later.
I had been using this product for the last two months and was going to right up a decent review until Monday morning, eight weeks after I received it.
I got this product after doing research on all the other HUDs that Amazon offered and this one seemed to do what I needed it to do. I drive a 5-speed 2005 Elantra and ordered this HUD based on it's display, the colors and information it presented.
When I received it, it seemed like a pretty basic setup; cable with ODB2 connector on one end and a mini-USB plug on the other, the device itself, a sticky pad to keep it from moving around on the dashboard (although, it was designed to lay on a flat dashboard, so if you have a curve over your instrument panel, it makes it harder to place and display the information correctly), and a polarizing sheet to eliminate the double reflection from the window.
I initially ran the cable along the outer edge of my dashboard, along the crack between the door and the dash, and then up under the dashboard to the ODB2 outlet to see how it would look. I noticed that the product lit up displaying the voltage and the word Hud. Cool. It works!
After spending about 30 minutes trying to translate the manual's very broken English and trying to work the settings controls (it's a 3 way switch - up, down, and in to navigate), I managed to get it configured for US measurements (MPH, Fยฐ) with two exceptions: the two over speed alarms and the fuel consumption information. Both of these are coded to only be in metric measurements (Km/H and Km/L, respectively) and you cannot change them. Since one of the variable displays is the fuel consumption information, I decided not to display this information. If you remember and understand that the values will be different than all the other measurements on the display, then you should be okay to display it.
I personally elected to display the RPMs, voltage, temperature (in graph form only), and speed. This gave me information about the car, without it being overwhelming. One good feature that this device has is the automatic display mode (menu option #7). When set to zero, the device turns off all other display information except the speed when traveling more than 50MPH (80KMH). This is very helpful and practical and make it so that it's not so distracting.
The unit has additional information to display, like the radiator temperature, mileage counter (i.e. trip computer), and alarms for when over revving the engine (i.e. you need to shift to a higher gear), over speed limit, engine fault, and fatigued driver. There is another "buzzer" alarm, but there's no menu setting to configure it. Maybe it's tied to the seatbelt, door open, or one of those types of alerts.
Once I had it completely configured, I didn't want it just hanging over my dashboard, so I disassembled my dashboard and fed the wire up thru the console's pathways to tidy it up. I applied the adhesive pad to the dash and plugged in the HUD. This setup worked great.
A quick note about how this looks. I always wear polarized sunglasses to get rid of the reflection of the dashboard and anything that is reflecting from it. This includes the HUD's box image. With the brightness of the HUD, this gives the perfect image of the information on the screen and, while the double image is there, it's not super annoying as long as I'm wearing polarized sunglasses. On sunny days, this HUD is tested to its limits and much of the colored information is washed away in the bright sunlight, but the speed is still noticeable, albeit faint. Other reviews of this same unit have recommended putting the reflection film on the windshield to allow the display to be seen better, but honestly, I have been hesitant to put anything more on the windshield which would create more of a distraction. However, if you've played video games, then the HUD shouldn't be a problem as the information is always present on the windshield and you don't have to look away from what's in front of you.
From commuting to running errands to just general leisure, it worked. I was able to unplug it and take it out of the car to prevent dishonest people from obfuscating with it. That is until Monday morning when was about to head off to work.
When I plugged it in after only 8 weeks of using it, each and every LED light on the display lit up and didn't show anything useful. I tried unplugging it and plugging it back in and even turned the car off and back on, but nothing helped. Basically, it died after only two months of use. After checking with Amazon customer service, I found out that the device has no kind of warranty at all, so if you buy one of these, be sure to get the extra warranty in case it craps out on you too.
Pros:
Easy to setup and start using
Bright display
Lots of information
Automatic reduction of information at higher speeds to reduce distraction
Various colors to differentiate different types of information
Con:
Doesn't include a non-stick pad for curved dashboards
It's a little bulky
The brightness can be a distraction if you are looking down at it while driving
Lack of adjustment to US measurements on fuel consumption and speed alerts
Settings controls are hard to manage and very touchy
To make it look nice, you have to know how to disassemble your dashboard to run the wiring neatly
Doesn't come with any stated warranty, so make sure you include one when you buy it
One thing I want to point out is the unit is not exactly as pictured and advertised, notes that the unit must sit directly on the dashboard, unlike some pictures that infer you can have it sit on the center console.
I have had no problems with any of the functions. I like the interface, it's smooth even with the complex settings and functions. Everything is completely custom at your discretion.
I really have no complaints. I am struggling to figure out how exactly to use the OBDII scan/function so I cannot speak on that.
***Also, PLEASE NOTE this will not serve as a replacement to a faulty sensor in your car. For example my coolant temperature sensor is bad, therefore this does not give me a reading for my water temperature. I am hoping this review can help some curious minds.

It doesn't have cardinal directions as the ACECAR does; it shows fuel economy, but in terms of L/100km, which is not especially useful in the US. The only potentially useful aspect is that it shows you real-time economy, so you might get some sense of your general economy. It also has a trip computer, which is helpful, but again, in km only, so, it's not going to be useful with respect to your nav unit, maps on your phone, directions, etc.
Engine temperature, in degrees Celsius, is also a useful reading, and may be consistent with your instrument cluster if you're in a European car.
Given that it is bigger, easier to read, updates its readings more quickly, and that all of the data displayed is helpful (although the color scheme is a complete mess and it's only in metric / European units), the reasonable price, and ESPECIALLY given the lack of better competitive offerings, this is a solid 4-5 stars as of June 2020. I'm opting to add this to all of my cars that don't have a HUD. It's simple, easy and useful.
