Use dark tint film as reflection day and night

Lots of features but no detailed description in the instructions. How to read or calculate gas mileage in miles or km/h. Easy setting to customize functions. clear reading

Speedometer pasted

First pluses: 1) Location and colors are easy to read. the writing is very small 2) The speedometer tends to get stuck at a random speed and won't go off until you turn off the engine, wait a few minutes and turn the engine back on. This happened several times. When this will happen cannot be predicted. I think it's a software bug. Your engineers should take a look. Better quality control is also needed. As you can see in the picture the speed is 49 mph but the car doesn't move at all. At some…

This display could be used in daylight and not too bright at night. It comes with a clear sticker for your windshield to avoid double vision but I haven't used it. I was actually very happy with the display. I bought it mainly because of the speedometer. For that it works great. Out of the box it needed some…

Pros
  • Electronics
Cons
  • New competitors have emerged

Okay let me explain, the instructions are really very strange and clearly translated into coarse English and quite difficult to understand. BUT if you get the settings right and go through the 4 MILLION settings it has and take your time, this thing works really well. You'll have to do a little trial and error to find out. It's also very responsive to revs and speed, especially when you set the polling rate to maximum (that's how fast the gauges update, so turn it all the way on if you can…
