Customer Reviews

Linda

"I picked up the WiiYii Car HUD C5 a few months ago and honestly did not expect it to be this useful. Seeing my speed projected on the windshield has changed the way I drive. I catch myself speeding way less on highway trips now. Setup took about two minutes."

"The P6 head up display is fantastic. I love being able to switch between display modes depending on whether I am city driving or on the highway. The fuel consumption readout has actually helped me adjust my driving habits to save gas. Great value for the price."

"I bought the WiiYii OBD2 gauge display to keep an eye on my truck's engine temps during towing. It reads everything accurately and the fault code feature saved me a trip to the dealer when my check engine light came on. Turned out to be a loose gas cap. Really glad I have this thing."

Frequently Asked Questions

What is a WiiYii car HUD and how does it work?

A WiiYii car HUD (head up display) connects to the vehicle's OBD2 diagnostic port and projects driving data like speed, RPM, and engine temperature onto the windshield using a reflective film. This allows the driver to see important information without looking down at the dashboard.

Will the WiiYii Car HUD C5 work with my vehicle?

The WiiYii Car HUD C5 is compatible with most gasoline vehicles manufactured after 1996 that have a standard OBD2 port. Some diesel vehicles and hybrid models are also supported. Check the product listing for a full compatibility list before purchasing.

What is the difference between the WiiYii C5 and the P6 head up display?

The WiiYii Car HUD C5 covers essential readouts like speed, RPM, water temperature, and voltage. The WiiYii Car HUD Head Up Display P6 adds fuel consumption data, trip distance, multiple display modes, and a larger projection area. The P6 is a good choice for drivers who want more detailed information at a glance.

How do I install a WiiYii OBD2 gauge display?

Installation is simple. Locate the OBD2 port in the vehicle, which is usually found under the steering column. Plug in the WiiYii display cable, start the engine, and the unit powers on automatically. No extra wiring or tools are needed.

Does the WiiYii HUD turn off when I stop the engine?

Yes. WiiYii head up displays detect the engine's ignition status. When the engine is turned off, the display powers down on its own. When the engine starts again, the display comes back on automatically.

Can the WiiYii OBD2 gauge display read and clear fault codes?

Yes. The WiiYii OBD2 gauge display can read diagnostic trouble codes (DTCs) that trigger the check engine light. It can also clear those codes after the issue has been resolved. This feature can save time and money on basic diagnostics.

Is the windshield projection visible during the daytime?

Absolutely. WiiYii HUD units include automatic brightness sensors that increase the display intensity in bright conditions. The included reflective film enhances clarity so the projection remains readable even in direct sunlight.

Where can WiiYii products be purchased in the United States?

WiiYii products are available through wiiyii.org as well as major online retailers like Amazon. Availability may vary by model, so checking multiple sources is a good idea to find the best deal.
