Heads Up Display for Cars, Digital Speedometer for Car A8 with OBD Function, 5.5 Inch Large Screen,Speedometer for Car for All Vehicles

I used in my Ford chassis camper because sometimes the regular speedometer was blocked by glare. It worked great.

I don't see what's not to like, other than the fuel efficiency, reading and leaders per hour or liters per 100 km, this is a great item, wish I would've purchased this year ago.I don't understand what all the bad reviews are about, but this works 100% for me so far, if that changes in the future, I will come back and revisit this review however, for now, this is a perfectly visible, crystal clear image on my windshield and everything works as it should! Definite buy

Unit never matched car information. Ex. Speed was from 4-20miles off, even after multiple calibrations. Other car systems could not calibrate and were useless. I do not recommend this in any manner. Not cool!

Like it, the only downside in the sunlight you see the reflection of the entire digital even the off ones

On one hand, I absolutely loved this display. It was very visible during the day and also not too bright at night. I really liked having the speed right in my view and the gas utilization which isn't available anywhere else on my existing dashboard.The thing that made me nervous is that the OBDII port is for diagnostics and isn't really supposed to be used all the time. I expected this to be a 'read only' type device (meaning, it is only reading the data and not sending anything back into the system) and it very well may be, but it turns out the vehicle doesn't expect that. Specifically, the car is sending data over the OBDII port that expects certain responses, and if it doesn't get them, it disables traction control and electronic stability control.Those systems shutting off isn't great, but it occurred to me that there is a small but non-zero chance that the car thinks it's getting a command to trigger some other part of the sytem (my greatest fear was the airbag going off while I'm zipping down the highway). I realize it's not a 'signal', but packet data, so the probability seems low, but still, even the tiniest chance of airbag deployment at any given moment is too much for me.

This item has been in service for about a month and is working well. It was easy to install and use. I was having difficulty with the manufacture's instrument cluster and could not see the gauges including the speedometer. This HUD has solved my problem and I actually prefer to look at the projection onto the windshield instead of the instrument cluster. The HUD is very easy to read even when driving into the sun. I placed mine to project just below the review mirror. This allows a clear view through the windshield in front of me and I can view the projection when I check the rearview mirror.

I like everything about it. It's easy to set up and use. Some areas of improvement will be a lip to not glare in my eyes while looking from the front seats. I can see the device projecting the information on the screen. Some models have a lip that keeps from reading from the device and the windshield. A longer charging or display cord may be useful. I wanted to place at center of my vehicle but it's a few inches shortI tried getting extenders but none worked

I have used it for about 2 weeks.It is easy to install. The cord is long enough and should fit any size car.Just make sure that your car has the OBD - 2 connector, and you should be fine.I am using it for my Nissan Rogue. The instruction manual is not great. Detailed instructions would have helped. I had to fiddle with it for some time and then I could change the settings like MPH/KMPH and adjust the Tachometer to be synch with the car. There are different display options. You can choose which one you like.All in all, great product. I definitely recommend it if you plan to buy.
