KAOLALI Universal Car HUD GPS Speedometer Head Up Display Digital Speed 3D Reflection for Cars Digital Speed MPH Overspeed Alarm

Not working well, gives wrong reading.

I like this unit because it not only shows the speed but the second option that it can show, and is selectable, is very clear as well. I have the clock showing. The secondary display shows in blue the speed shows in white. It does not require any HUD film to be stuck to the windshield because it has an adjustable HUD attached to the unit. The gps speed is easy to adjust to my speedo.

Llegó dos días antes de lo previsto, superó la expectativa.. Puedes cambiar el estilo de la pantalla, se apaga automáticamente... Compatible con Sonic. Parámetros precisos. Totalmente recomendable.

I really liked this thing. The clock appears to only work in 24 hour time, but I have enough clocks that this is not even to the level of "minor annoyance". The speedometer matched my phone GPS out of the box with no calibration and the glass panel is slick with enough brightness to be visible when the sun is shining directly on it.My problem is that I bought the unit primarily for the odometer. For some reason Dodge didn't see the need for a trip computer on the '65 Dart, and I use it to keep track of fuel economy. Took me a few days to realize that I was not actually getting 45mpg out of my 58 year old car. When you adjust the units of measurement, it only adjusts the speedometer side. The trip computer is still measuring in kilometers. Also, it has no onboard memory so every time you turn off the device it resets to zero. Too bad, otherwise it's good enough that I am seriously considering just keeping it and doing the conversion when I calculate.

Difficult to set up but once programmed is fairly good... Can't get to set other than 24 hour clock... But not that big deal... Not accurate on elevation of that is important item for anyone purchasing this item... At least I couldn't get it to calculate accurately...

Don't waste your money. This product is junk, it doesn't keep time after you turn off the vehicle an turn it back on . It's a 24 hour clock which I hate. the mph is not accurate at all. You can adjust it but no matter what you will always be 3 to 4 mph off . Lastly the GPS signal absolutely sucks, you be driving and you'd lose signal and the unit goes to 0 until it finds GPS signal again. I do not recommend this product
