  • Plug and play easy install! Plug and play easy install!
I’ve been using the Wiiyii OBD2 HUD P6 for a few days now, and I’m honestly really impressed with how much value it offers for the price. Setup was super straightforward—just plug it into the OBD2 port and it powers right up. I didn’t have to mess with complicated wiring or calibration, which was a big plus. Within minutes, I had real-time data showing on my windshield. The display itself is clear and easy to read, even in daylight. I especially like being able to see my speed, RPM, and coolant temperature without taking my eyes off the road. It adds a nice layer of safety and convenience, especially on longer drives. The overspeed alarm is also a great feature—it’s subtle but helpful for keeping things in check. Another thing I appreciate is the dual OBD + GPS functionality. Even when OBD data isn’t perfect, the GPS helps keep the speed reading accurate. It feels like a well-thought-out backup system. Overall, it just makes the car feel a bit more modern without spending a ton of money. If you’ve got an older vehicle or just want more real-time info while driving, this is definitely worth picking up. ... show more

  • Worked Great - Was Skeptical
Bought it for my 2026 Mazda CX50 to function as a turbo pressure gauge. It works great, also had the various other screens shown. Just wish you could change the colors to match each cars general interior lighting. But the next closest option was either a manual vacuum gauge or the AEM x series which is $181 plus luring equip. TLDR: great value for the price, beats more expensive manual vacuum assemblies and more expensive big brand alternatives like AEM. Only cons are size and lack of gauge color modifications. ... show more

  • Functions fine (not as well in a Rav4 prime though), absolutely garbage manual Functions fine (not as well in a Rav4 prime though), absolutely garbage manual
Bought this to get a tachometer functionality because some people on a forum recommended this to get a tach for a Rav4 prime. The issue with the Rav4 prime (and not so much with this HUD) is the battery voltage is super inconsistent. Sometimes it's over 14V, sometimes its at 12.8, 12.9V, and it can interfere w/ the voltage off, so unless if you're okay at working out some inconsistencies with this display, maybe don't get one for the Rav4 prime (I mean, the product description says it's not compatible w/ hybrids). The mounting tape wasn't very strong, and the suction cup was initially not "suction" at all until I took the proper time to get it suctioned on the window, and it has held itself in place ever since. There's an included screwdriver to remove the bottom plastic plate that you adhere the double sided tape to, I opted to removing that after getting the suction cup working properly, and used a piece of tape so the little remaining plastic bits have a soft place to sit on and doesn't damage the dash. 3 control buttons lets you to cycle between different display modes/entering into the settings/switching different readings on subsections of the HUD, and you're able to see readings like coolant temp, oil temp, transmission temp, turbo boost (if your car has a turbo), there's not too much customization, but there is a blanket reading page that just shows everything possible, if you need something like that. What is absolutely awful and not an excuse however, is the manual. There's like...no instructions on setting the manual, and it feels like half of the settings don't even do anything. There's also no way to disable certain warnings, like "high coolant temp warning", the only thing you can do is set it to an ungodly 200C. It also seems to shut itself off after the specified voltage after 3min regardless of what you set for the timer to turn this OBD2 off, at least that's what I assume what that setting is supposed to do, but there's no manual to tell me that. Given the price, this would absolutely be 5 stars had the manual actually detailed what all the settings did. ... show more

  • Very nice addition for monitoring vehicle information.
This is a nifty little gadget. Various display mode allows me to pick the type and data I want to see. It fits snuggly on the corner of the dash board. I use it to display oil, water, CVT(*) temperature in real time. In the first try, the timed auto-off didn't work and it stayed on. It turns that I also need to set the auto-off voltage to >13V. Then it will turn off when the engine is off and after the set time. The logic is a bit odd but it worked. I bought one each for my 2018 Forester and 2020 BRZ. I do need to tweak the speed by 2~4% so the reading matches the digital speedometer on the BRZ and the Garmin navigation on the Forester. It reads "CVT" temperature on the Forester. But on the BRZ 6MT it also has a "CVT" temperature readout. I am assuming it is just the temperature of the transmission gear oil? I wonder if there's a way to rename it or somehow they just use CVT to represent all types of transmission. ... show more

  • Provides very useful information on car performance
This is a great device and I like it a lot. I would have given it 5 starts except for a couple of issues that I think may be the reason why this is shown as "frequently returned". I think most users did not fiddle with it enough to make it work really well. I admit, my interest was perhaps a bit different from others so I was motivated to make it work. Here are the issues: 1. The "users manual" is almost useless. It is written by a non-native English speaker and is very cumbersome - if you can read it at all. It has very tiny text so you need a magnifying glass to read it. 2. The clock function is designed for international use so only shows 24-hour time values (14:30 = 2:30 PM) 3. Setting the clock is confusing unless you realize that it uses GPS time which does not know the loca time zone. You cannot set the time exactly. You can only set it within 30 minutes and then the GPS will figure out the time zone. 4. My car does not have a tachometer, compass or any engine instrumentation (it is a KIA pug-in hybrid) so I needed this to provide information from the OBD2 plug (it has a direct, wired plug-in - not bluetooth - which makes it much easier to use. Also, it does have the ability to show error codes and to clear the codes if needed so this is a plus. For things not in OBD2 (is has no magnetometer), it uses the GPS which is a great combination. It will also work in GPS mode only if you don't need the engine instrumentation. 5. The ad says it will not work with a plug-in hybrid (I didn't notice that) or on trucks, etc. It seems to work with anything with an OBD2 port - even pre 2009. I have a 2006 and 2008 Ford truck and it works great on both of those. 6. I love the shape and the suction cup mount. I put it in the very upper-left corner of the windshield where it is out of the field of view for driving but close enough to read even the small fonts. 6. However, it took a lot of fiddling to make it work with my KIA but it was worth the effort. The instructions for auto turn-on and turn-off (by time or voltage) still do not make sense to me but by continuing to tweak the values, I was able to make it work and now it does everything I wanted. ... show more

  • Works great!
This little thing is awesome. I have a scan guage iii that I use for some specific monitoring. But for the basics, I'm not sure that this can be beat. What triggered the purchase was that my Transit van will not allow me to adjust the speedometer to match larger tires. This little baby with its speedometer adjustment function let me see my real speed without having to do math in my head. It also shows me transmission and engine coolant temperature. Important to me as I drive forest roads and like to keep an eye on those two. It's also readable in sunlight, which I was initially concerned about. Haven't tried it at night yet ... show more

  • Well worth the price.
It helped me determine I have a faulty vehicle speed sensor / transducer in my Land Rover Discovery 1. The speedometer was showing normal but what was being reported to the ECU (accessed via the OBD2 reading) was way off and all over the place causing shuddering and loss of power. The problem was intermittent and viewing a code scanner would be very challenging to catch the problem. For about $40 tax included it’s well worth it for just this reason. But, it’s also really nice to have digital readings of coolant temperature and voltage. This era of Land Rover is notorious for the factory temperature gauge not moving until you are already overheating. ... show more

  • Great addition if your car's dash board is lacking information Great addition if your car's dash board is lacking information
Although I generally wanna say I'm completely satisfied with this item the fact that you can't change the 3 parameter/gauge setting is frustrating. Many others have this complaint as well and I wish something can be done so you can have the ability to change it and not just have it set to Volt Meter. It's super easy to set up and all of that and provides crucial information that your dash cluster may not. At night it's nice and bright and can be easily read. I have peace of mind now driving around my 2008 Honda Fit now so I'm happy 😊 ... show more
