wiiyii Heads Up Display for Cars, Digital Speedometer for Car A8 with OBD Function, 5.5 Inch Large Screen, HUD Speedometer for Car for All Vehicles (OBD2 Speedometer A8)

Large, brite read out. Very easy to install. I read some reviews that the speed didn't match the speed odometer. If you buy this unit, be sure to download an owners manual from online. It is model A8. Then you can calibrate the speed and RPMs to your car or truck. Also explains how to operate it.

Very good product performance, but it completely failed after a year and three months. It continuously resets as if it is just powering on. Seller ignored my messages until I reported that to Amazon. After more messages, seller offered a 20% credit. A 2-year warranty implies replacement, not pro-rated adjustment, like tires are. Seller continues to ignore my messages, and although I've reported this to Amazon repeatedly, I haven't received a warranty replacement of the item. Just so you know what to expect if you have problems . . . .

It's working well. I love it 💕

Initially it was reading 3 mph faster than it should. I was easily able to adjust the speedometer to match GPS and vehicle speed perfectly. I wish the fuel usage was in gallons per hour and mpg, and not in liters per 100km and liters per hour. It also would be better to be able to see voltage and temp at the same time. The temperature bar would be better used as another numerical digital readout so you could see exact temp and voltage at the same time.

Compré este display especialmente por la información de temperatura del motor. Hay veces que me distraigo del millero, pero con esto resuelvo definitivamente mi preocupación. Valoró el artículo desde su presentación. Bien empacado, bien organizado, se ve bien. Ofrece muchísima información y va directamente conectado del OBD. Creo que el precio es un poco exagerado en comparación con otros en el mercado, pero este definitivamente ofrece toda la info que necesitas del millero. Puedes elegir qué informaciones poner. Yo particularmente dejé solamente la velocidad y la temperatura

Thought this could be a nice add on to my 2001 Pontiac, but kept turning itself off. Tried in a different 2001 vehicle and had the same problem. Tried one more time in a 2010 Jeep and it worked with no issues. Instructions are crap for convertingout of the metric system, but found a YouTube video simplified things. Wished it worked with the vehicle I wanted it for.

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

Don’t even bother. Does not work and gets stuck on HUD. The poor reviews / rating on this product say it all.

Received on time. The quality is great. Installation was a breeze. It would really help if they can put it clearly which side of film goes on which side on the windshield. The brightness during the day is amazing. However its ultra bright during night time. I am using it on 2013 Lexus LX570. I have to turn it off during night time. I thought it had an auto feature where it dims when its dark out. Other then that its a great product. Oh yes, the kms are not 100% accurate. It shows speed 5km faster then the car is actually going.

Pro: Bright and clear without even during bright sunlight. I didn’t have to use the sticky film for the windshield. Cons: Speedometer not accurate about 6KM off. Doesn’t display fuel rating, rpm also hit and miss. It’s bulky on my 2023 VW GTI since there aren’t any cutout or slope to hide it like in Mazda 3 GT it’s sits on top of the dash doesn’t look that good. Wish if its little thinner. No height adjustment of the display so it’s sits very close to windshield. I wouldn’t recommend this HUD for newer VW GTI.

Cela fonctionne bien , mais de temps en temps il decharge completement ma batterie et j,ai finalement du l'enlever et il a fini a la poubelle.

Its stop working properly after a while shuts off and resets while driving over and over .
