Car HUD, MPH Speedometer, GPS Heads Up Display, Universal USB Port Compatibility, Dual-Mode GPS+BDS Signal, Automatic Brightness Adjustment, Speeding Alert Function

Very quality product. It takes some time to initiate when you connect for the first time. But overall quality and working is excellent. I am very happy with the display. Very useful while driving on expressways where there is ceiling on the maximum speed allowed. The display is bright during daytime

Bad

Buzzer Sound too low

I decided to give this HUD a shot after paroosing Amazon for one, and I'm so glad I did! Firstly, setup, while a bit confusing, is easy to do once you read the manual. Secondly, if you purchase a mount for it, it makes it MUCH more functional. Thirdly, it's auto brightness, GPS connectivity, and reliability all work flawlessly! I did have to adjust the speed to be -1 mph to match my car, but that's pretty typical for most cars I believe. Honestly it's as if it came factory with the car! Didn't even have to use the reflective film on the windshield because it gets bright enough. Also the speed warning beeps are annoying so I just set mine to over mph and it will never bug me again (unless I can somehow get my Odyssey to go 200 mph LOL). Overall very satisfied!

This handy little gadget works well overall, though it does seem to read about a mile or two per hour higher than my actual speed. I’ve used it during both daytime and nighttime driving, and the display is bright enough to see clearly even in the harsh Texas sun. At night, you can easily dim the brightness for more comfortable viewing. Switching between miles and kilometers is simple too. The base sits securely on the dashboard without any adhesive. So far, mine has stayed firmly in place, even when taking sharp corners on purpose. The unit itself feels solid and well made, and it has handled the Texas heat without any issues. I also like the customizable speed alarm that alerts you when you exceed your set speed, and the built-in compass is a nice bonus. The only downside is that the directional letters on the compass are fairly small and can be difficult to read at a glance. One of my favorite features is being able to keep my eyes on the road instead of looking down at Android Auto. Since my truck’s factory speedometer is inaccurate due to oversized tires, this has been especially useful for me.

Really easy to set up and very functional! The numbers are easily readable in all light levels, and not too bright at night. I love the simple design and navigation, and I love that you can control whether the device makes noise or not. There is a setting that will make the device beep repeatedly if you hit or surpass a certain speed, and the default value is 75mph. This is a nuisance on road trips when on interstates that have speed limits of 80mph, so it was helpful to find out that I could edit the speed it checks for or even turn off checking for a certain speed. When you hit the designated speed, it will beep several times and then stop beeping, but the numbers will flash as long as you're at or over that speed. When you hit the speed again (either coming down or going up), it will beep several times again. This is nice as an audio indicator of your speed if you like that, and would be good for situations like a teen learning to drive. The default speed accuracy was off by about 2mph (over my actual speed), which you can easily adjust in a setting on the device to get a perfectly accurate speed reading. This connected to GPS very quickly and easily for me once I plugged it in. For reference, I live within city limits of a medium size city and within range of multiple cell towers. Connectivity and connection time can vary depending on your location. This doesn't connect if my car is in a structure like a parking garage, but will connect shortly after leaving the garage. Overall, this is a wonderful value. I'm very happy with this purchase! It would be nice if it was wireless and powered by solar (since it already sits on the dash), but I'm happy with it as-is.

Overall a great product. Takes a minute to connect to a gps satellite and might take some calibration a ting upon first setup, but having the hud is worth it! I've got the green lit hud that also shows direction of travel, which is nice. The base it rests in is a silicon thing with a non-slip base, about as non-slip as it can get for not using any adhesives, so sharper t I runs can move the hud. Only things I could suggest for this would be programming the menu to not needing to be reflected as most folks will likely be holding it in-hand when adjusting settings

good
