Surprised at the accuracy of this little speedo. My suburban is lifted up with oversize tires so just adding this thing saved me on speeding tickets. I'm gonna buy another one for my 66 fairlane.

Not only is it easy to install, there are a few options. It only comes with a 12 volt (cirette lighter) male plug for power. But you can remove the cord and then substitute any type of USB power source you want. This was important for me because in my car, the USB C ports were in a place where I could easily hide the cable. The USB 3 and 12 Volt were not and would have been ugly if I had to use them. I was going to return this until I found this out. The other things I like about this is that it isn't to large a display and it has a bit of a "hood" so you don't see the reflection of the display in the windshield above the unit. (I haven't checked at night, yet.) It also doesn't have any chrome which would also reflect in the windshield above.. Well thought out and good value.

After spending over $600 dollars chasing down the bugs in my Toyota Camry speedometer I purchased the digital gps hud. This is all I needed. End of story.... wish I had thought of buying one earlier.

I tested this with a known accurate speedometer and itâs balls on accurate. Small enough, looks good and mounts easy. It also nice that you can pick all the colors and what you want displayed, I have it set to display speed, time and voltage and all are accurate. Sometimes the time takes a few seconds to update when first turned on and occasionally I have to unplug and plug back in in order for it to display, the screen will just look white. Would buy again works great.

This unit has some compelling features. For example, for me, its size and the ability to mount it on the top of the dash right near the windshield makes it (almost) the ideal solution. Unfortunately, it's accuracy leaves me scratching my head.As others have mentioned in their reviews, initially the readings compared to 2 other GPS's was pretty far out. No problem, sez I, I'll just adjust the setting in the menu and that will be that. Not Quite.I spent a fair amount of time doing the adjustment, and yes, I was able to adjust it to exactly match the other 2 GPS's at highway speed (60 -70 MPH), but it was off at low speed. So I readjusted it at low speed to exactly match. Again, perfect speed match at 25 MPH, but off at 70 MPH. The bizarre thing is, it can be too HIGH at high speed and too LOW at low speed! Or, too LOW at high speed and too HIGH at low speed, depending on how you adjust it. Really weird.The best i can do after way too much time playing with it and fudging the adjustment at one end or the other is good accuracy at 70 MPH, and off by about 1 MPH at 25. (Or the other way around). The "turnover" point is somewhere between 40 and 50 MPH - above that the error is in one direction, below that it's in the other.Now, normally I wouldn't make a big deal out of an error of 1 MPH. However, this thing's supposed to be driven be a GPS device, and at a constant speed they just aren't normally consistently off in one particular direction (or change the direction of error at some point).I recently threw together a GPS display using a Wemo D1 Mini, a GPS module and a small display, and never saw errors like this unit has. (In the first place, there was NEVER any need to create a method to fudge the speed display, because the speed from the GPS module is a given - unless you're not tracking enough satellites, or there is multipath or a weak signal, the speed is the speed, and you don't have to compensate for anything in the unit.)So, I don't really have a clue why the speed error is there, but I'm wondering if it has to do with rounding errors in the display routine - instead of rounding to the nearest MPH perhaps they're truncating the number - who knows?Anyway, as I said, its a compelling item. I just wish I could believe the displayed speed a little more.
