Great item, you get exactly what you see
I’m still getting to know this item I purchased it so I don’t have to take my eyes off the road to look down, I also purchased it so I can get a little bit more information than my Honda Ridgeline provides on its dashboard such as oil pressure/temperature.Seems fairly accurate. The MPH is off one or two when you get up over 60 mph but I believe I can adjust that.Good value for the money, good quality, not great but good, the design itself could be better, but that is what it is, it doesn’t look bad a little utilitarian, but I’m in a pick up truck!Numbers and letters are easy to read from a display is small so you’ll need to put it as close to you as possible, but it’s perfectly visible at night and the self adjusting brightness helps with visibilityOverall, this is a highly functional unit, that will be a good addition to your vehicle

Works perfectly as a cheap digital speedometer in an old Toyota.
I wanted a digital readout for my older car and this seems to be working great, you need to make sure you have the right port to plug it into as I don’t really trust the “GPS readings” they say it can output but if you can read it from the cars computer it works great.

Inaccurate product
Tested with another reader I have and nothing this thing says is accurate. Temp is off many degrees. Speed is way off. It says my alternator is charging at 18 amps and I a voltage test and it’s at 14.25Very hard to readVery very cheap plastic feel.

Had to return
The things it would display were good but it wouldn’t display any of the things I purchased it for. Navigation and temperature displays wouldn’t work. Ended up returning.

Great, versatile, add-on gauge.
I have a newer car with a digital speedometer and I came to like that feature so much that I wanted it in my older car. Also, I’m picky about what I add to my car interior because I like it to look mostly factory/original. This gauge looks quite professional and it can be mounted 4 different ways.I gave it 4 stars because it’s menus and instructions are not very intuitive so it took some trial and error to set it up the way that I wanted it and I had to calibrate it (through the menu) 3 times before it matched the reading on my OEM analog speedometer. And I had to fiddle with the settings to get it to turn off when the car is turned off.But since I did all that it has worked seamlessly without issue. It has an auto-dimming feature and I can read it in bright sun, and then it dims to about the level of my dashboard illumination at night. All in all, I’d buy it again.
The boo boo –
