Car HUD Head Up Display 3.5 with OBD2/EUOBD Interface Plug & Play Vehicle Speed KM/h MPH, OverSpeed Warning, Water Temperature, battery voltage, mileage measurement - Blue

Junk, I be went through all of the function, nothing is staying in memory base, keeps flashing my voltage. Totally pissed off, A complete waste of time and money.

Unit would not operate with mph only kwh.

Just installed on my 2013 Hyundai Accent GS and it's looking great so far works with and I'm parked in the sunlight and it's like 1:30 in the afternoon, so you can get an idea of the brightness calibration, is easy for my car, no longer comes with that holder thing anymore that blacks the view of the display so you can only see it in the windshield. It now is raised on the edge that faces you, so the holder is no longer needed, so that's cool all in all pretty satisfied.

The MPH speed is way off. No matter how adjust the setting, the speed accuracy is off by 5-10 mph at best. The speed in KPH is accurate, but I am not used this.

Installation was a breeze, comes with a black flat cable that connects to the car computer, easy to hide and a reflective film. In my case, I found it unnecessary, so I removed it. Initially, the speed was not accurate, but following the instructions, it worked perfectly. If you are looking for a simple HUD to see the speed rate, at a super low price, look no further, this is it.
