I did ask a question of if this product is compatible with F-150 2016 Ford, they said it wasn’t ! That was after I bought it! Believe it or not! It is 100% compatible and once you dial it in to exact specs your ready to go! Great product for 2016 F-150! Enough hackberry length for the job! I ended up using Velcro instead of the rubber non skid pad included! ### ⭐⭐⭐ It's ok *by L***G on Reviewed in the United States on 5 August 2024* It gives me speed, and that was what I really wanted. The rest is ok. My biggest issue with it, is you can see the unlit segments. I'm going to see if I can apply a screen that will only let the light from the segments through. They are bright enough to handle a little dimming from a cover screen. Fuel consumption is metric only. So, that's useless. Temp is ok, but not something I really need on a HUD. I can also see it on the instrument cluster clearly. My main need for a HUD speedometer is the fact that it is hard to see the speedometer gauge on my car when my hands are properly placed on it. This way I can glance at the HUD without leaning my head to see the speedometer on the cluster. As for the HUD visibility itself and performance, it is not as good as a native HUD. A native HUD is recessed in the dash, and the displayed data appears to float out near the end of the hood. This means you don't have to readjust to looking at it vs the road. With this HUD, you have to refocus on it and then refocus on the road. Also, the reflective windshield application does not look great. It is dark, and only partially see through. I tried not to use it, but I got reflections on both inner and outer glass surfaces, giving a double image.Like I said, this thing is OK. ### ⭐⭐⭐⭐ HUD Display *by K***E on Reviewed in the United States on 20 July 2021* Nice unit for the money. However, it is really about having accurate data provided to the vehicle operator. The speed of the vehicle is off from the HUD digital indicator by about 4 MPH at 60 MPH. I am not sure why. The car internal display and the HUD should match since the data comes from the same sub-system in the vehicle. The ODB2 data is provided to the car display as it is also sent to the HUD unit. So why the difference?It would be nice to have data logging in the unit such as using a Micro SD card. It could write a CVS string to the SD card on a preset interval. This would allow commercial users to get the card and understand how the vehicle was operated. By using CVS data strings, any number of software applications (such as Microsoft Excel, or Google Docs) could read the data and create a history of the vehicle.It should be noted that the display is not a normal LCD monitor but rather a flat panel with high intensity LED lamps. While it does work, perhaps a LCD monitor with a high NIT output would be more useful to the driver. The driver could choose what data they want to see and where to see it.Anyway - for the price it is not bad. I would be willing to pay more for a far more useful HUD system. ## Frequently Bought Together - KAOLALI A8 HUD Display 5.5" Dash Screen Projector OBD2 Auto Gauge RPM MPH Speedometer Overspeed Warning Fuel Consumption Temperature Speed Heads Up Windshield Display Multiple-Color Bright for Cars - LISEN Retractable Car Charger 4 in 1 [69W USB C Car Charger Adapter] iPhone 16 Car Charger Fast Charging, Gift for Men Women, Car Accessories USBC Car Charger for iPhone 16 15 14 13 12 Android, Gray - chcela 60W USB C to USB C Cable [3Pack] iPhone 15 Fast Charging Cable,6ft Long USB-C to USBC Power Cord for iPhone 16/15 Pro Plus Pro Max, MacBook Pro Air/IPad/iPad Pro 12.9/11,AirPods 4(White) --- ## 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.co.uk/products/445822468-kaolali-a8-hud-display-5-5-dash-screen-projector-obd2](https://www.desertcart.co.uk/products/445822468-kaolali-a8-hud-display-5-5-dash-screen-projector-obd2) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
