Car HUD OBD2 Gauge,Head up Display for Car,Digital Speedometer for Car

The best HUD out there. Not too big. Easy to setup and use. Mph is about 2 mph off from the OBD reading in all my cars. Definitely worth buying though.

My unit came with both a "cigarette lighter" power cable and the OBDII cable and both are of more than sufficient length. First I tried it using GPS mode and it worked as expected with a slight delay. I'd say this would be acceptable for freeway speeds but not so much on surface roads where you adjust speed more often. Then I tried the OBDII port and that works GREAT! The unit instantly reacts to acceleration changes and appears to be accurate once you reduce the speed setting by about five points. My car has a "stop/start" system so the unit would turn off when at longer stop lights but instantly turn back on when the engine engaged again. I changed the setting to wait two minutes before shutting off and I think that has addressed the issue. The light sensor seems to work well automatically adjusting between full daylight, tunnels, and nighttime. There are several functions that the device can show when connected to the OBDII port but I just want speed and time. On that note, the most annoying thing is that time is shown in 2400 format vs AM/PM, there is no option to change that. Oh and the user manual really needs to have a native English speaker edit it. The unit can also be switched between miles and kilometers in the settings. I like how this unit has a semi-reflective panel built-in. IMO, this is superior to those that require a reflective film to be placed on your front windshield or the ones with a solid display that block your view of the road. I do think the buttons are a little "fiddly" but once you have things set-up, you rarely ever have to touch them again. Overall I'd give this HUD a 4.5 out of 5 but Amazon doesn't allow half stars so 4.0 it is.

Este equipo es fantástico. Inicialmente me decepcioné, porque conectado al OBD2 la velocidad varía demasiado y no es precisa al menos para mi camioneta, pero en el modo GPS es super preciso y en mi caso, que quiero que me marque unos 5km/h por debajo, para que no me sorprendan los radares de velocidad, con la recalibración disponible es posible sin problemas. Lo tengo desde el 2022 y ya van a ser 3 años. Tuve cierto inconveniente con la película reflectiva de la pantalla traslúcida que se fue borrando, no sé si debido a algún líquido de limpieza de los que pone el personal de las lavadoras, pero cada vez se veían menos los números. Esto lo pude resolver en un negocio de láminas solares para autos, donde me cortaron una tipo espejada a la medida de la pantalla y quedó como nuevo. Desde entonces todo ha sido felicidad y créanlo o no, mis multas de radares por exceso de velocidad han disminuido a casi cero. De hecho, yo quería comprarme un detector de radares pero ya no creo necesario invertir tanto dinero en eso. Una cosa que me preocupaba mucho, al usar yo el equipo solo en modo GPS, era si iba a tener cobertura satelital en los lugares de difícil acceso que visito, donde usualmente no hay señal celular y resulta que me asombré de encontrar hasta 12 satélites conectados. No sé cómo funciona esa cosa, pero hace su trabajo increíblemente bien. También he podido comprobar que sirve para borrar las luces de check engine del tablero, una vez que me apareció una, luego de desconectar la batería. Le dejo las 5 estrellas porque me parece un gran producto y espero que usen las ventas que eso pueda generar para mejorarlo y aplicar las sugerencias de los clientes. Las cosas que sugiero que mejoren son obviamente la calidad de la película reflectiva y también de la alfombra adhesiva, que tuve que cambiar por otra mejor al dejar de fijar al equipo en su sitio. Tanto la brújula como la altitud sobre el nivel del mar funcionan muy bien también. He probado la altitud tanto al nivel del mar como sobre los 3000m y todo bien. Espero disfruten tanto como yo este equipo. Recomendado 100%!

This was fun for awhile. Until it stopped working! Always said I was doing 5mph faster than my GPS said I was going... Then it had glitches and finally would not work anymore. I got 5 or 6 moths of use from it. Now its garbage. YMMV

This is on the HUD-C5 unit. Want to really like it BUT it’s kinda hard when box is sent with the usb cord, the cigarette lighter adapter, and the instructions manual all MISSING!!! And to top it all off it was received more than a week late hence the major reasons for 4 stars removed. Playing with the little I could check and understand without the manual, the brightness was ok out of the box, speed was off by 5mph, engine rpm’s were off by 500, buttons were sticky, odb2 plug hard to remove when unplugging it (but I guess that’s a good thing since you won’t have to worry about it disconnecting to easy). They were nice to offer manual in pdf and small discount but it wasn’t enough to offset my having to buy the adapter and another cord and waiting even longer (so much for giving it as an Xmas gift).

The C5 was easy to install , only on the OBDII since my Sorento 2024 has it . The fact that the C5 glass is not that tall made it perfect for the placement in front of the dash and it is perfectly level with my eyes without interfering with the road ahead . . I needed to adjust the speed from the 107 factory set to 102 but after that it is spot accurate . The display is very brilliant and I can see it clearly during the day with no problem at all . It is as I said before, very brilliant so the display is perfect . Very much recommended and the price is great , too .

Clears fault code only in OBD mode. Not sure how to get the Altitude display. GPS mode gives very erratic speed readout. Instructions not very good.

Used this to replace my speedometer. Works great. Needed to setup for GPS though as it is not compatible with the communication port. Setting it up is a bit of a pain, the instructions are mostly helpful but are not properly translated in spots. Overall works great once setup with GPS.

Having a digital speedometer right infront makes looks at the speed while driving a whole lot safer. Connecting through the GPS and USB cable was easy setup. The stick pad it came with is very good at sticking on the dashboard without leaving any tape residue. The brightness of the light projection is clear and visible at bright daylight as well. There was some issues with my OBD wire, but it works well under GPS settings

We have a 2015 Citroen C1. The device connects to the OBD2 port under the steering wheel, finding that was the hardest part. Plug it in and off you go. I went through the settings (once I'd blown up the instructions which required a magnifying glass at my age) and found things basically ready to go out of the box. I had to route the cable up to the dash where the device sits, that will depend on your car of course. My only complaint would be that in the dark there can be a little reflected light on the windscreen but not enough to distract me from driving or obscure my view, I think that's what you get from not having a built-in unit which projects on to the windscreen itself. The final result looks like the pictures and means I don't have to take my eyes off the road to check my speed or see the time which is all I wanted out of it.

⭐⭐⭐⭐⭐ Review Title: Great HUD with One Annoying Buzz—Easy DIY Fix! ⸻ Review Body: I really like the Wiiyii C5 HUD—clear display, good features, and great value for the price. However, when I first installed it, there was an annoying buzzing/rattling noise coming from the unit, especially noticeable when driving over rough roads or idling. After some detective work, I discovered the source of the buzz: the four control buttons on the top plastic cover were loose and rattling inside the casing. This is a common issue with this model but totally fixable with a simple DIY hack. ⸻ How I Fixed the Buzz: Tools and materials: • Small pieces of soft foam or felt (I used leftover foam from a previous car project) • Double-sided 3M tape (optional, for better adhesion) • Small Phillips screwdriver (if you want to open the case carefully) Step-by-step: 1. Unplug the HUD and carefully open the casing by removing the screws underneath. (If you’re not comfortable opening electronics, you can try this with the unit assembled but opening it is best.) 2. Locate the four buttons on the top plastic cover. These buttons have some play and cause the rattle. 3. Cut four tiny pieces of thin foam (about 1–2 mm thick) to fit under or around each button. 4. Stick the foam pieces under the buttons to gently press against them and prevent movement but still allow normal button presses. 5. Use double-sided tape to keep the foam in place if needed. 6. Reassemble the HUD carefully and screw it back together. 7. Test the buttons and listen—the buzz should be completely gone! ⸻ Final thoughts: This fix transformed the unit from annoying to excellent. If you buy this HUD and notice a buzz or rattle, don’t return it immediately—try this simple mod first. It only takes 10–15 minutes and uses cheap materials you probably already have. Now it’s silent, functional, and a great value for the price. Highly recommend!

I was pretty excited for this but when I opened the box the wires going to the obd reader were disconnected from the hookup and since I don't have standard USB ports in my truck the device is useless to me. Other than that looks exactly like the add and sure it'll work well too

Working well in 2012 Hyundai Santa Fe CM Diesel. A little bit of fiddling to mount it right where I wanted it, lined up on dash. But no dramas. Great to have adjustment for speedo in settings. Update 2026 Bought another usit for a new car - ISUZU MUX 2025. Installed and tested. Happy with all the same features except can't get Speed or RPM from OBD. GPS works perfectly for speed, and was able to be adjusted to be quite accurate. As speed was the main feature, am still happy with the unit and accept that maybe there is something in the way ISUZU passes the Speed and RPM through the OBD port. A bit of research resulted in finding the following (symptoms appear to be an ISUZU issue): Modern Isuzu architectures require your scanner or app to be set to auto-detect or specifically ISO 15765-4 (CAN 11/500) rather than legacy OBD protocols. App/Software PIDs: Generic OBD apps often fail to poll Isuzu-specific proprietary sensor addresses; try changing the profile settings in your app to use specific Isuzu/GM diesel or standard SAE generic PID sets. Baud Rate & Sleep Settings: Bluetooth or Wi-Fi adapters can bottleneck data streams; adjust your adapter's connection settings to a faster update rate or reconnect the adapter with the ignition fully turned on before launching the software. Perhaps Wiiyii could address this in a software/firmware update?
