YICOTA 5.5" Original High Definition Car HUD Head-Up Display Advanced Windshield LED Projector Fit for OBD II EOBD System Model Cars (A8)

I found it very tough to set up correctly. It’s actually still sitting the box and not being use!

I havent tried the fuel mileage but i dont really care. It pays well with my after market ECU but sometimes the tac will get stuck or will flash out wvery couple of minutes. No problems ever with the speedometer always acurate even at high or low rates of speed. Only down side to this is is uses up you obd II port but to most thats an upside meaning plug and play instalation

I have had the unit installed for about a week now. Unless the sun is shining directly on the unit, the readability is very good day and night. I like that I don't have to use any adhesives on my dashboard to install the unit. The mat that it sits on stays in place without having to be permanently secured. As for accuracy, I have been tweaking the settings for the speed and RPM and I haven't really found anything that is 100% accurate (when compared to the dashboard). Speeds up to about 55 MPH are relatively accurate. Anything above that is 1 to 3 MPH higher than actual dashboard speed. RPMs are off by 200 to 300 (below what is reported on the dashboard). Not all of the items that is supposed to be reported appear on the unit. This really isn't an issue for me as I normally only show the items I care about (speed and RPM). Overall, it's worth the money.

My 01 Bonneville is OBDII compliant but this HUD does not seem to work. It boots for 2 minutes, and then I can briefly enter western data, and then it boots again. My Bonneville is OBDII compliant, and current scan tools can read all the data, but this cant so far.

Starts out in metric, speed is inaccurate. Instructions could use improvement and require a magnifying glass to use

I enjoyed it it worked well gave me all kinds of dad I didn't have a 4 it looks good on the window

I installed it on my 2005 Durango and everybody remarks how cool it is ! I took my time installing it to make it look factory like my 2004 Corvette very bright also! I definitely would buy another thank you fast delivery too!

Dont waste money

What a fab little gizmo. This was only going to be used for a little while until I had my faulty cluster replaced. Well. Its still on the dash of my car and is my main speedo. I absolutely love this. Its made driving safer (I never look at my dash any more.) and a lot nicer. It has too many functions to list. But it will cover most essentials. Water temp. Speed. Battery. Status. Fuel consumption etc. Its bright and clear even in direct sunlight. I hope to use this well into the future.

Läuft alles wie beschrieben abschaltautomatik funktioniert, nur der drehzahlanzeiger aktualisiert sich etwas langsam. Es ist auch ohne spiegelfolie gut ablesbar, sowohl tags als auch nachts.

Davvero ottimo head up display.Appena installato riconosciuto subito e funzionante. Senza dover cambiare i parametri del dispositivo. Facile installazione.Ah già diversi giorni che lo sto testando, risultato soddisfatto dell'acquisto fa il suo lavoro indicando tutto il necessario.Montaggio facile basta collegarlo alla presa obd2 sotto il volante. Il cavo è abbastanza lungo più di 1.5 metri circa quindi si può posizionare dove lo si vuole nel cruscotto. Allego una foto nel mio caso. La mia auto Opel corsa 2017

Fait son boulot, la réflexion de l'affichage se fait très bien sur le pare brise.Je déconseille d'installer le film adhésif, même si l'affichage est un peu dédoublé car l'adhésif n'est vraiment pas esthétique sur le parbrise de l'auto.En journée, si il y a beaucoup de soleil avec angle direct sur le parbrise on ne voit pas rien.Si vous avez des lunettes de soleil, vous ne verrez rien non plus quasiment.Mais la nuit, ou lorsque le soleil ne tappe pas sur le par brise c'est excellent. Surtout la nuit, la où l'attention doit être maximale.Par contre, veillez à ce que l'appareil d'affichage ne soit pas dans champ de l'oeil car l'éclairage est assez fort et peu gêner la conduite .. et oui ... c'est en rien de l'holographie mais de la réflexion. :) Je recommande. Prise OBDII.

It works very good
