Review: 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. Review: 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 ## Features - SAFE IS THE FIRST----Just focus on your driving, could read speed at a glance with the digital numbers but without having to look down; This unit simply displays directly to you at whatever angle you set it up, no need to make effort to have a look, which may lead to make distractions or even cause accident. - NEW DRIVING EXPERIENCE----10 kinds interface, free switch, LCD meter, clear fault code, read data stream; 2 install way with adjustable bracket, put on dashboard or stick to windshield, easy operation, non-destructive installation. - A MUST HAVE----If you don't want your driving record to have points on it or pat hundreds of dollars in speeding tickets; If on a major highway, you really want to know how fast you are going; If your wife get worried and want to see you're not driving so fast as she feels; Or if you would like to solve your problem of never knowing how fast you are going, this speedometer perfectly matches your need. - DRIVING MORE COMFORTABLE----When driving normally, the ambient light is blue color(automatically adjusts the brightness according to the environment ); when driving abnormally, such as speeding, the ambient light will be changed to Red color for alarming. - MORE SMOOTH & STABLE----Common meter only has OBD mode, but ours is dual mode: OBD+GPS 2-in-1, the default display OBD+GPS function at the same time, and data display is more abundant. OBD system, can read more than 100 kinds of data in the car. If the vehicle doesn't have OBD2 protocol, only displays GPS function. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0957S3F3H | | Best Sellers Rank | #8,112 in Automotive ( See Top 100 in Automotive ) #2 in Automotive Speedometers | | Brand | wiiyii | | Brand Name | wiiyii | | Customer Reviews | 4.0 out of 5 stars 2,400 Reviews | | EU Spare Part Availability Duration | 7 Years | | Item Dimensions | 5.24 x 3.54 x 4.33 inches | | Item Weight | 190 Grams | | Item dimensions L x W x H | 5.24 x 3.54 x 4.33 inches | | Manufacturer | wiiyii | | Material | Plastic | | Material Type | Plastic | | Model | P6 | | Number of Items | 1 | | Part Number | P6 | | Thread Style | Dual | | UPC | 765530746162 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** wiiyii - **EU Spare Part Availability Duration:** 7 Years - **Item Weight:** 190 Grams - **Item dimensions L x W x H:** 5.24 x 3.54 x 4.33 inches - **Material:** Plastic ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61kIJ+NWj6L.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/71BhlgxtyQS.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/71byf04lgdS.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/81Cu9VREz6S.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/71gQkbXDTlS.jpg) ## Questions & Answers **Q: Will obd work on a 2000 Chevrolet blazer?** A: Did not work on my 2006 Chevrolet Tahoe. **Q: Es compatible con Honda accoord 2010 ?** A: Si es compatible **Q: Funcione para cadillac escalade 2004?** A: Si funciona para este carro **Q: Does this work with a 2009 Daihatsu Boon?** A: Works on any vehicle with an OBD2 port.

Haven't tried it at night yet ### ⭐⭐⭐ Functions fine (not as well in a Rav4 prime though), absolutely garbage manual *by O***S on November 30, 2024* 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. ## Frequently Bought Together - wiiyii Car HUD Head Up Display P6, OBD+GPS Smart Gauge, Works Great for Most Cars - bbfly-A9 OBD II OBD2 16 Pin Splitter Extension 1x Male and 2X Female Extension Cable Adapter (2FT/60CM) - bbfly-B6 OBD2 Splitter 16 Pin OBD II Splitter Extension 1x Male and 2X Female Extension Cable Adapter (1FT/30CM) (1Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/322685617-wiiyii-obd2-gauge-display-heads-up-display-for-cars-car](https://www.desertcart.vn/products/322685617-wiiyii-obd2-gauge-display-heads-up-display-for-cars-car) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
