Speed limits — blank beats wrong
Uses the map's real maxspeed when there is one. When nothing is certain the sign stays blank and no warning sounds; turn on “Estimate” to infer it from road class and Circular 31/2019, always marked ~ estimated.
Map, speed, the speed-limit sign, clock, lunar calendar, music and dashcam on one screen. Install the APK and go — offline maps of all of Vietnam keep working without signal.

All worked out from GPS and map data. Plug in an OBD-II dongle if you want readings straight from the car.

MapCar takes reports from drivers in all 34 provinces and cities: speed signs, enforcement cameras, jams, crashes, flooding… A sign shows only once three different devices confirm it; incidents expire on their own after 30–60 minutes.
Join the Facebook group to ask about setup, show off your car's screen and suggest features.
Open Google Play on the head unit — or copy the APK to a USB stick, download it on the unit → press Home, pick MapCar Launcher → “Always”.
Your browser reports older graphics (OpenGL ES 2.0) — the buttons above now point to the build for older head units.
