Heads up Display for Cars Car HUD M7, Digital Speedometer for Car OBD/GPS Smart Gauge, Driving Speed, Engine RPM, Voltage, Water Temperature, Etc.., Speedometer for Car 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!

Works with my 2025 Acura TLX. Shows speed, rpm, battery, fluid temps from the OBDII port. Now I need to see how long the device lasts.

This is one of my favorite devices I've ever purchased on. Or for a vehicle. Especially how it keeps my Attention in front of me. So that way I don't have to look away from the street.

It was amazing at first, this was the coolest gadget to add to my older truck. Only reason for buying it was because my wife’s car had the HUD from factory, and it was helpful. Bought this one, and it was perfect. Worked flawlessly for many months until a recent trip I went on. A simple 4hr trip and now this thing is glitching like crazy. Instead of your speed, it keeps jumping through other settings like battery voltage and its other features. I keep unplugging it and plugging it back in to no avail. It was cheap, so maybe I’m expecting too much out of it. But it didn’t last a year of use. Otherwise it was pretty cool and worked as described in the beginning.

Awesome product, but is defective. Multiple units stop working abruptly within 7-14 days. Otherwise it’s handy.

This thing once you set it up properly is amazing! Speed limiter does work! Miles per hour was off by 2mph had to dial it back to get thee accurate setting! I've got mine connected to obd2 in my 2014 ford fusion and it works flawlessly! Battery voltage rpm shows up nicely when I shut the vehicle off! Takes 20 seconds to shut off after you shut your vehicle! The only down side I have on this is the reflective plastic piece that sticks to your windshield! The complaint is I drive at night and that can make it seem brighter then it needs to be so it becomes a distraction! I chose to just use my windshield and it works just fine day and night!

Very cool upgrade for great price. Makes it easier to keep my eyes on the road, I put it next to my radar detector to be able to monitor both readings without having to shift my eyes back to the main dashboard away from the road. It was really easy to install Just plug and play. Definitely worth the money. For my Q50 the reading is within 1 MPH of my dashboard speed.

The pros: easy installation and good display visibility. The deal breaker is accuracy. It's fairly accurate at low speeds, but once you get above roughly 40mph, the display is off by 3-4mph. Has anyone found an aftermarket HUD that stays consistently accurate? Judging by reviews, that seems to be a problem across-the-board.

2015 KIA Sorento. M7 works perfect right out the box.

Bought my first one of these on one side of the world 5 years ago, and it’s still almost completely functional. Now I’ve moved to the other side of the world and bought it again - I love being able to see my speed on the dash. Wouldn’t bother with the reflective film on the windscreen as I don’t see the point. Also remember to take the film off of the unit’s display itself as this will improve the reflected image. If you think it’s not bright enough, turn off auto brightness and set it to max - for me its completely visible in everything but bright direct sunlight.

Fonctionne tres bien, agréable a utiliser, aurait apprécié un précision que le collant reflecteur allait dans la vitre lors de la lecture des instruction

very good

Works well, except the cable for the OBD connection is a bit too short to do a proper installation.Had to run across the dashboard instead of hidden behind the pillar.
