ACECAR Digital GPS Speedometer, Universal Car HUD Head Up Display with Speed MPH, Compass Direction, Fatigue Driving Reminder, Overspeed Alarm HD Display Meter, for All Vehicle (G4)

For what I need this does work. Living in GA and with the tall trees, winding roads you can't really tell what direction you are traveling especially if you are new to the area. The only problem I have and this may not totally be the units fault is after 45 mph, even with setting the 102 code recommended, the unit isn't synching with the car speedometer. The car is about 5 mph lower than the satellite reading. Having said this, it also could be my speedometer as my vehicle is over 20 years old.

Loved this product when I got it. But you get what you pay for I guess. The device failed due to the USB socket on the device detaching from the circuit board inside the device. Would've rated higher if it lasted at least a year. ☹️ Beware if you want something that is going to last.

I have a rail buggy and wanted a speedometer on it. It works great and pretty accurate as well.

Would be nice to have instruction that make sense. This one is so vague you have to experiment with the device to learn how it works.

Hola, muy buen producto.Se puede mojar? Tolera el agua? porque lo uso en motocicleta.Gracias

Take the time to set it up correctly and this is a great little speedometer. I use it because I have non standard tires on my vehicle so my speedometer is off at higher speeds. I downloaded a gps speedometer app on my phone to calibrate against. To make it fit I bought a right angle adapter for the cord so the cord comes out of the side of the unit.

First one we got the usb plug pulled out with in minutes. Got a replacement and same thing. Display was nice for the couple of minutes while it lasted.Update:Seller did reach out and try to make it right before offering replacement.

I installed this in my 1995 Honda Acty Street Van. Tested it in my 2017 Tacoma and speed is accurate. The GPS picks up satellites relatively fast. The display is clean and the device is very flat so it doesn't take up very much space. The brightness is not adjustable as far as I can tell (I didn't read the instructions), but is good for both day and night. I also installed a USB power supply to my ACC Power line to the device only powers on when I have the car on.

Muy buena calidad capta los satélites sin problema bastante exacto, muy claro muy satisfecho.
