CarCode Speedometer

The product works as described, and the brightness is never an issue, as the reflective plate allows it to display clearly even in direct sunlight. The downside is that the speed is consistently about 5-6 miles per hour too high. If Android Auto shows 60 mph, and my dash shows 96.56 kph, this product will show 66 mph. I would like the offset addressed, but otherwise it works well.

I like that’s if bright enough to see in daylight/full sun. Didn’t like how it didn’t come with any instructions and i couldn’t link to the instructions on line.

Easy to install and use. Accurate sped measurement.
