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

Had a hard time figuring out the settings ! After I got it configured it’s just simply Bad Ass !! Accurate & Fun to look at travel time , wind speed etc !! Great Device 👍👍

I really like this gadget and I have purchased three of them. I particularly like that it has its own display rather than having to put reflective film up on the windshield for other HUDs. At first the speed displayed was several miles per hour faster than the actual speed as displayed on the car’s speedometer. This is no problem as you can adjust the displayed speed to match that of the car’s speedometer. You do this when stopped, by pressing straight in, the little switch on the right side of the device, and then you press the switch forward or back towards you thereby adjusting it up or down by how many mph it’s off.

Everything seems amazing. It's a really good product. I adjusted the speedometer setting from 107 to 102 and now it's very accurate. Also many complain that the screen is unreadable in bright light. My experiance the screen cannot be read only when the sun shines directly on the screen, (it's on my motorcycle). However, all I do use my hand 's shadow to shade the screen and it is easily read.

Slightly above a toy quality. But they look great in flea market race cars

I recently installed this HUD in my Audi Q5, and I'm thoroughly impressed! The setup was easy and straightforward, with a clean, modern design that integrates seamlessly with my dashboard. The display is clear and easy to read, even in bright sunlight or dimly lit conditions, thanks to the adjustable brightness and the reflective glass that ensures visibility without being distracting. The information is projected directly in my line of sight, making driving much safer and more convenient as I no longer need to take my eyes off the road to check my speed or other essential data.Another feature I love is how sleek and low-profile the unit is—it doesn't obstruct my view, and the compact design blends in perfectly with the aesthetics of my car's interior. The responsiveness is top-notch as well, with no noticeable lag when updating information. Overall, this HUD has been a great addition to my Q5 and has significantly enhanced my driving experience. Highly recommend for anyone looking to upgrade their vehicle's tech without breaking the bank!

White speed indicator hard to see in bright daylight otherwise unit functions great. Blue LEDs easy to see. Red function indicators easy to see also. I like the milage and time elapsed functions. Great for taxi fare calculating

Once calibrated, this thing is spot on. I’d recommend getting in your car and matching the speed of your vehicle as a reference point. I put this in my golf cart. Would definitely buy again.

Had looked for an accurate magnetic compass for a vehicle for awhile, and all of them came up short.Forget installing a magnetic compass for an auto (too much metal to be accurate).THIS compass is THE ONE -- at a very affordable price!CONS: Awful instructions in extremely tiny printPROS:Everything about it is great -- once you tough your way thru setup.--Bright, large display is easy to read--Ability to configure information YOU want on the display--Accuracy with time, speedometer, compass and altitude (able to calibrate). Readings are based on multiple satellites and the info is rock solid.
