Car HUD Head Up Display M7, OBD/GPS Smart Gauge, Driving Speed, Engine RPM, Voltage, Water Temperature, Etc.., Works Great for All Cars

A quick TLDR; here at the beggining, I love this device and would highly recommend it if your even considering trying it out. It's definitely worth it!Now to go into a little detail about it. At first I was worried that this would not show up/reflect well off of my windshield like I wanted to have it do. However, this package came with not only a grippy mat, but also a reflective sticker, more like a cling, to put on the windshield to enhance the reflection. This works really great and I added two pictures of what it looks like in the worst of times (direct sunlight) as well as the best of times (in shade). It looks great and is easily readable at both ends of that sunlight brightness spectrum.The reflective sticker is sort of closer to a cling, with one side sticking better that the other which made it easy to figure out which way to put it. Also, since it wasn't extremely sticky, I was able to replace it numerous times to get it in the exact spot I wanted. If I was going to nitpick something, I would've liked this sticker to be slightly bigger, but it does show the whole display when placed perfectly. The reflective sticker also does not allow anyone to view the display reflected on the windshield from the outside.Plugging this into the OBD2 port was pretty self explanatory. The cord is flat which makes it easier to route between plastic dash covers as well as push it down into the dash so it's pretty much not visible for me and looks like it's built in the way.The menu navigation was a little tricky to figure out while having it installed, so I would suggest getting all the settings done before you route your wire. Once you have it in though, I don't really see any reason to mess with it. It turns on extremely fast as well so there is no waiting for it to start up once you start the car. It's ready to go as soon as you are.The size of the unit is okay. It would be nicer if they could get it to be a little thinner, but ultimately it's completely fine as-is and is out of the way. As for durability, I have only had this unit for a couple of weeks but haven't had any issues. I will come back and update this review if it ever stops working. I have pretty high hopes for it though.Overall I'm extremely happy with this purchase. I bought it to bring in a digital speedometer to my Ford F-150 as I got used to a digital display in one of my other cars. At this price point, it really does a great job!

This USB speedometer is exactly what I needed for my 80s car with a faulty speedo. Installation was incredibly easy, just plug it in and go. No wiring, no complicated setup. It picks up speed quickly and accurately, even compared to GPS apps, and the digital readout is clear and easy to see while driving. It’s a great modern solution for older vehicles where mechanical gauges are unreliable or hard to replace. If you’re driving an old school ride and want a quick, dependable way to track your speed, this is a solid upgrade.

Works great in a DMG shell. Seems to work alright, a bit slow to get a connection but seems to be accurate once it does.

It's a very nice device (while it works), has the minimum I really needed for an HUD (to show the speed in the windshield so that I don't need to take my eyes off the road while driving), but the longevity is pretty bad. The device looks good, works good while it's brand new, and it might keep working if I would remove it from the car every time I get off, and I just plug it back in when I get back in the car, but if it's left inside the car, I believe the heat damages it and it would just stop working (by showing 0 in the speed, or simply not showing anything or just get stuck showing any random speed you were doing when it failed).Right now it just doesn't work at all and I'm stuck with 2 of them that are just completely broken and I have been unable to find out about the warranty for this item.Save your money until they develop a better version that would last longer. And I have to say I was using it during spring, when it wasn't really that hot (higher probably in the 70s, lower in the 40s), but we know that cars get hotter while parked under the sun, and it just no longer works. I'm unable to return it as it's been over 30 days when it failed and I'm left with 2 broken devices that worked great for a few weeks.

Didn't last after a year. Mph switches to kph, keeps shutting down and restarting and other malfunctions

When it arrived I was surprised how small it was but small is good so it doesn’t take up much space. The size of the digits are easy to read. My speedometer on my vehicle is not accurate so I wanted this for a fast easy glacé to see the speed. Upon a cold start, it usually has to connect to enough satellites before it will work. I think it will grab the satellites much faster if your outside and not moving but even if your moving and it takes a mile or two, that’s fine for what I paid. I really like it. One item that wasn’t so great were the instructions for calibrating the speed for it to be accurate. Mine was off maybe 2 miles an hour and i basically had to go for a drive and keep tweaking the adjustment. I personally did not understand the amount to adjust each time so I just guessed and road tested and it took 4 or 5 adjustments before it was good. It’s been fine since.

A lot smaller than I expected. Have a mileage blocker on my BMW to keep the resale high and this is much better than looking at my CarPlay screen.

The media could not be loaded. Full disclosure: we returned this item because it wasn’t quite what we were looking for, but I wanted to do a review because it’s an amazing product with a lot of great features.If you’re like me and have a car that only displays kilometers, this is a great way to compensate. Driving in the USA means I need a way to clock MPH.Not only does this HUD do that, it also offers several other features like brightness adjustment, speed parameters and alarm that dings when you exceed them, a clock, and a fatigue reminder.It’s easy to operate and understand, too.It comes with a dash mount and the in it is adjustable. Plus, the USB cord is long enough for you to position it wherever you want to in your car.Great device at a great price and packed with a lot of features!
