Easy to connect, easy to use. *by D***T on July 5, 2021* I picked this one because you don't have to have all the extra garbage on your windshield. All I wanted was the speedometer. Simpler looks more stock anyway. I ran only the speedometer the first few months, only recently did I turn on the RPM line (pictured). I like having that option. I can add more too if I wanted, but overall, HUDs look better when they're simpler. If I want to know more about my car, I'll use my dashboard or bluetooth OBD reader. Instructions were simple, and in english. Not sure why so many are having issues with this step. Picture looks a little blurry but it actually looks better than that. On the brightest days around noonish, it is a little harder to see, but still visible. This can be alleviated by using the included darkened transparent film. After a weeks, I put the film on to try it out, but in the end, I removed it. I prefer the look of my windshield without the square on it and I really didn't need it anyway. At night, it's very bright. I took one star away because of the "auto" setting for brightness. I mean, it's the only real option unless you want to change it manually all the time. I feel the brightness should have several levels of Auto. At noon-time, at it's highest brightness, I can see it, but I feel like it should do better to be more usable in that scenario. On the other hand, at night, it's brighter than it needs to be. Brightness settings should not be 1, 2, 3, or "Auto." It should be Auto 1, Auto 2, or Auto 3, which each being brightest for daytime (because it'll never be too bright with the sun out), but a dimmer night setting. Like each Auto 1, Auto 2, etc could be a differently level of dimmness at night. That's a problem I find with most chinese electronics, not quite bright enough during the day, but too dang bright at night as if they're compensating at night for what they can't do during the day. Overall, I do recommend this, despite my one complaint. My complaint is common among all HUDs so if you had to choose one, pick this one. You will have to fiddle with the settings to get it calibrated to your vehicles speedometer but it's not hard, you just gotta read the instructions. Most of the bad reviews on here are because no one wants to read instructions. They plug it up and then complain. ## Frequently Bought Together - ACECAR Head Up Display Car Universal Dual System 3.5 Inches HUD, Speedometer OBD2 GPS Interface, Speed, Engine RPM, OverSpeed Warning, Mileage Measurement, Water Temperature, GPS Mode for All Vehicle - bbfly-B6 OBD2 Splitter 16 Pin OBD II Splitter Extension 1x Male and 2X Female Extension Cable Adapter (1FT/30CM) (1Pack) - OBD2 Right Angle Splitter Y Cable Male Splitter to 2 Female Extension Cable 30cm/12 --- ## 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.sn/products/117973131-m7-dual-system-hud-hot-sale](https://www.desertcart.sn/products/117973131-m7-dual-system-hud-hot-sale) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-04-24*
