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 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!

I like to have the display, but I return this one because I wanted the one that had more information on it. It was easy to use and plug in and try to find a right spot on the dashboard to set it so it’s comfortable to your eyes so you don’t have to move your head a lot, everything is great

This unit has been installed for about 3 days, now. It seems to have issues with accuracy. When I am stopped (even for a long duration) this unit fluctuates between 0 and 3 MPH. This is when completely stopped. This issue seems to follow suit no matter the speed. It seems to always be 'hunting' for the actual speed. I have used many aftermarket HUD units for a few years, now. This is the only one that seems confused. After many attempts to adjust the setting for MPH it remains inaccurate. It wanders in it's speed... sometimes slower than actual and other times faster than actual. Completely unreliable.

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.

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

So much good stuff with this unit. Suction power for mount is excellent ! It has the newer style double cup base, so when you install on windshield it stays there ! Unit takes maybe a minute to find satellites average around 12 to 15 satellites acquired 19 most I have gotten. Have checked accuracy against known good speedometers is right on the money ! The display is a backlit segmented display (not sure of proper name) all the different parts of display are visible and only the ones selected are backlit. I use speedometer, compass and # of satellites available. Has a clock but I never got it to set (I didn’t read instructions!) Unit has one button on top used to cycle threw all available display options. Unit has power cord (no power supply) has to be plugged into a usb power source. Display is ease to read with my 67 year old eyes with no glasses on. Last but not least unit is very affordable I paid $27 and change (had a coupon) so I highly recommend this unit !!!

Update: Compass works well, need to get it out and moving. Don't judge it by moving it around in your living room.Five stars._________It just arrived, I got this for the altimeter and compass, don't really need another speedometer. Altimeter seems ok, compass points N no matter what way the box is orientated. I'm hoping once I get this driving around the compass will come to life. I'll reedit this once I know for sure.
