KKmoon Car Heads-up Display, Universal Car HUD Head Up Display KM/h & MPH Speeding Warning

I've install this in the car but I'm not sure if I can adjust it to work correctly. Very hard to get everything lined up so that the driver can see the display without looking up or down. When no sheet is fitted there is a nice clear image on the screen, but because car screens are laminated you get two images, but as soon as you fit the screen reflector to the glass the image is not as clear.It's also difficult to line things up, also cable comes out at the front car screen, would have been better coming out the car side and straight down to the socket.I've ordered a reflective holder and hope it fixes the problem.Next is the set up, once you manage to understand what's to do, it's easy there onwards.Not as good as I had hopedWatch this spaceUpdateIve now bought a reflective phone/hud holder, you place this device inside it and it has an angled mirror screen, Now I have fitted this inside that extra unit, the display is good, this device isnt much use with its plastic sheet, too small and visible outside and bad display.So if your buying this, first order that device that you can use this with ;"Universal Car HUD GPS Navigation HD Image Reflector" £12Now that you have both, im wondering why you would want to see the cars voltage, or engine temperature? perhaps you do? I don't, I bought it to see the speed, as the 60 isnt clear on my car. The setup is a bit confusing, but Im sure you will eventually figure it out, mins in MPH now, and a flick of the set switch you can switch off engine temperature and RPM leaving a nice clear MPH in the mirror display.It suppose to display other things? I think it did when turning engine off ? Well MPH is all I want, but does work out more expensive as the reflective plastic is of no use. A mirror would be ok?UpdateAdded photo of that hud holder without it this device is no good at allHelpful?Yes,NoThanks

Great for seeing the digital speedo on the windscreenBecause you can’t speed the car speedo all the time.Battery voltage and engine temperature can also be displayed but not both at the same time. Revcounter is also handy having a alert buzzer.I’ll buy one again if I had two cars. .

Good little fun gift, took me awhile to find a setting that was accurate. Easy to install.
