Free delivery on eligible orders. Review: Works very well, may need adjustment - Bought because the speedometer on a new car becomes invisible in bright light. Crazy, but the manufacturer seems to have designed it so the backlight goes off as the ambient light brightens. Since they also made the numbers off-white and the background pales grey, on a sunny summer day you have no precise idea how fast you are going. Its basically a safety hazard, and with camera enforced limits of varying speeds its impossible. This fits nicely in the corner of the windshield and shows the speed very clearly in large white digits, its not perfect but its fairly visible even in the brightest of sunny days with the sun shining directly on it, and 95% of the time its very visible. Two cautions. One, you need to check whether the digital display matches the speedometer, and if not, adjust it. This is a fairly simple process, explained in the user guide, and it works. In my own case the digital display was reading a little slower than the speedometer (which is bad, it could get you a speeding ticket), but setting the gain factor to 110% fixed it. The manual is written in rather odd English, but its understandable. Two, on modern cars the natural place to mount it may have a sort of non-stick coating preventing the sticky pad from working properly. I used blu tack, which would not stick to the top of the dashboard, but did to the drivers side pillar, which works fine. There is rather more cable than is needed for this location, so just gather it up with cable ties. Altogether this is excellent. It also has lots of other possible information displays, seems to be everything one could want, but I haven't tested them, only wanting the speedometer function. Review: For Smart ForTwo W451 2010 model - MHD drives have possible issue where the alternator belt can snap Since there is virtually no over temperature indicator on this model, I bought this to give abnormal overheating alarm so as not to destroy the engine.

Works brilliantly ### ⭐⭐⭐⭐ Delivers what it claims to do *by A***N on 22 November 2018* Connected without problem, only real fault is cable is a little short. A little slow to update MPH and RPM displays but they may be because my car uses the slower ISO 9141-II protocol. The case could be smaller and made of better quality plastic but it works pretty well ## Frequently Bought Together - Head-Up Display X50 Plus Car HUD Speedometer Car Alarm Car OBD HUD Multi-Function Digital Meter Driving Computer Display with LED Head Unit, Scan and Clear DTCs for 12V OBDII Diesel Vehicles - 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.kr/products/53047247-autool-x50plus-car-head-display-digital-obdii-speedometer-with-over](https://www.desertcart.kr/products/53047247-autool-x50plus-car-head-display-digital-obdii-speedometer-with-over) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-09*
