JUST COMPARE THE SPEED ON YOUR STANDARD CLOCK AND ALTER. SETTING 1 ON THE MENU. **Q: Is this device saft leave it plugged in obd2 all the time ?** A: I have had no issues whatsoever and been very pleased with the unit.

And sometimes it would stay on even when the engine was turned off. For this reason I had to return it because I was worried it may kill my battery. ### ⭐⭐⭐ 3.0 out of 5 stars OBD 2 doesn't work in my car, SAT works well. *by A***R on Reviewed in the United Kingdom on 26 May 2019* I bought this mainly to give me a accurate speed limit in my UK 2006 Toyota Landcruiser LC5 when driving in europe(km's).Apparently my car is not obd2 compatible. It still works well using the satellites but you loose it in tunnels.Still better than nothing. --- ## 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.pt/products/126716244-ma-way-car-head-up-display-obd-ii-gps-interface](https://www.desertcart.pt/products/126716244-ma-way-car-head-up-display-obd-ii-gps-interface) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-17*
