wiiyii obd2 Gauge Display Heads up Display for Cars Car HUD Head Up Display P6, OBD+GPS Smart Gauge, obd2 Speedometer with Speed,RMP,Water Temperature,Overspeed Alarm,Works Great for Most Cars

★★★★★ Excellent addition for my 2007 Toyota Prius! I bought this for my 2007 Toyota Prius because the factory dashboard does not include a coolant temperature gauge. I wanted an easy way to monitor the engine temperature and make sure everything was operating normally. Installation was very simple. Just plug it into the OBD-II port and it starts working immediately. The display is bright, easy to read, and shows important information like coolant temperature, engine RPM, and battery voltage in real time. It has been working perfectly, and the temperature readings have been very consistent. This gives me much more confidence, especially on long drives and when climbing hills. If you own a second-generation Prius or any vehicle that doesn’t have a factory temperature gauge, I highly recommend this device. Great value and very easy to install

I have been an avid car "gadget" guy for years and for the most part have disappointed with my purchases in the past. This one was a very pleasant surprise, worked exactly as promised, simple installation. 5 STARS!!!

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.

My car doesn’t have oil temperature gauge. It’s nice to have some extra gauges, especially after making some modifications to improve the performance of my car. Had to dial in the speedometer. I wish I could change more of the gauges. Some are locked in, but you can change a few of them and there is quite a few different display choices. It will help you figure out your stopping distance and your zero to 60 times. Mounting and hiding the wires were easy with the tools given with the gauge set. A decent size I don’t have any problems reading the gauges. It looks pretty good in the car too. I want to minded it to be a little bit bigger and have more information available to me. The voltage meter is nice and it has a lot of gauges that my car doesn’t have. I can’t tell you about durability because it’s been about six months. I turned the brightness of mine down, so the display would last longer.

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.

This meter has worked perfectly in my truck I like it because it is very easy to install and perfect for when we go on a trip and we do not want to make any mistakes its data is exactly real so it is really something indispensable.

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.

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.

色々多機能がありカッコ良い

I have been using this now for over 2 years in wife's Hyundai ix35 and now in Tucson. Wife primarily relies on this for speed and I found it very accurate with car speedometer. I used the window suction mount option as it is easy to install. There are so many display designs and other data from car's computer which one can find handy. Brightness is perfect. I use google maps or Waze for actual speed as all cars speedometer is always higher than actual speed. This is not this device fault.... most people don't know this. I will highly recommend this product

Ótimo produto

My Car is a Chevy Corvette 1988 C4 so this product doesn’t fit because you need to buy an extra extension cable or cord, I didn’t know that until my friend showed me, we’ve tried it in his Dodge challenger and we connected it with any extension 👍🏻

Would like to buy one more. Awesome stuff
