Pretty good composition of the review and good install directions.

Philip Rush says:

Sucks ass

Average Apmoc Gaming says:

Ok so i bought one and it stays on HUD and the fuel gage lights going up and down. What does that mean ??

Bob Plus says:

Seems fuel consumption does not work.

Mukesh Awasthi says:

Useless invention

Jonathan Owen says:

Mine doesn’t want to SYNC… It turns on and stays on the HUD logo and voltage of battery only, it then turns off after a few minutes. MY Car is a Toyota Vitz (2005)

Gerald Jerico Velayo says:

Scotty sent me here too

Motto Cleveland says:

crap … bet your insurence goes up for that crap!

chebrneck says:

The reflection shows the entire device not just the display. Kinda cheesy

The Sky Pod says:

Dont know if I would place it so high up on the windshield . And needing the reflective screen would be a bummer if you want to move for another driver.

Philip Rush says:

This is ass

Chrstphre Campbell says:

It’s a very cute idea; but with the loose cable and all the peripheral reflections on the display glass; it all comes off as kind of slovenly ! / i kept hoping that the instructions would allow the user to embed the unit -into- the dash, and hide the cable inside the dash console ? so that it looked much more integrated as a final presentation device ? ( ? )

Mannaf Raju says:

not so safe,,

MFProductions says:

Is it just me or does this look like a ticket waiting to happen? If I am driving a the police see this light on my windshield especially at night, its “you got some ‘plaining to do Lucy”

Mark Cantillon says:

Will this work on a 2009 Jaguar XF 3.0D?

Paul Amaro says:

Nice video! I found it to be helpful!

Harmon Wood says:

I would think that at night it would seriously interfere with one’s vision.


Thank you very much for sharing. What make and model car you did the installation to at the time of the video?

John Smith says:

Mazda 3 2010 will it work if I buy one

Alternative Headlines says:

Totally impractical while driving. No way I can send texts and look at the HUD at the same time.

Art Garcia says:

Hi, base on your review which one do you think is the best HUD for overall quality and features, even looks and lights? I can’t decide which one to buy

Dino Carroll says:

Great instructional video. I bought the unit and installed it with no problems. My only concern is that the unit will not turn off automatically when I turn off the ignition. It displays the “HUD” logo and battery status and seems to be in “scan” mode. Is there a way to reprogram this function so that it will turn off once the ignition is turned off? Thanks for your help!!

Philip Rush says:

Instead of a H.U.D display you should have said a reflective display. It’s ass by the way….

bonjour j ai une Toyota aygo est ce que ce système serait compatible avec ce produit ? merci Allwin W02 LED Car HUD Head Up Display OBD2 Interface Plug/Play Speed Warn System –

Art Garcia says:

I think the placing of RPM squares is not right, 1k rpm is at 5th places, but the 2k rpm should be, but its at 4th place

J Striker says:

I think it would look better if the windshield film was cut so you don’t see the edges of the device in the reflection.
It could be done if you can see the reflection in the film (before you take off the final protective layer)

sterrissar says:

nice clear review helped me to make my mind up thanks

Rodel Hermano says:

This is horrible. It is more of a distraction.

Daily Youtuber says:

The Eng. Temp. is at Max


is it me or does it seem laggy??

Long Beard says:

Nope. I’ll stick to my free app on my phone and scotch tape on the very bottom of the windshield to reflect hud image.

Tibor Végh says:

Very informative video, thanks!
