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

Stupid easy to install. I should have bought this years ago. It basically shows you all the data an obd2 reader will tell you with the additional of height above sea level, gps, mpg, brake test, 0-60, etc. It’s a great tach. It worked perfectly on my 2007 Toyota.

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.

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 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.

"This product works fine overall, but some functions like RPM and other features aren’t working properly. Even the clock isn’t functional. While the speedometer works, the high price makes it not worth the money. I think avoiding this product is the best option."

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

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 👍🏻

Y a un relais qui a sauter à quelques part derrière mon tableau de bord si bien que tout les cadrans et mon système de chauffage climatisé d'habitacle sont H.S.! 😭 Mais en installation c'est appareil formidable j'ai plein d'information que j'avais pas avant a part les RPM et la vitesse, j'ai maintenant le voltage de ma batterie avec l'alternateur voltage de charge,pression d'huile moteur, température, du liquide de refroidissement, consommation en litre au 100km ,un odomètre, aussi il s'éteint tout seul quand le moteur est coupé, aussi il lit et effacent les défauts sur l'obd2... nous avons aussi l'heure mais surtout j'ai enfin été capable de corriger ma vitesse qui était plus lente de 7% très facile à re calibrer avec les fonctions de configuration maintenant je roule à un véritable 100kmh en affichage et 100kmh en réalité avant sa indiquait 107kmh et ma vitesse réel était de 100kmh .🤩
