Off-road without an atlas,
with an app instead.
NavX4 is the off-road navigation for everyone who wants to be free and ride terrain legally: real routing across gravel roads and trails – for 4x4, overlanders and travel enduros. More gravel, less doubt, all the fun.
The vision: be free. Ride the terrain. Legally.
The best roads are not in your street navigation. NavX4 finds the unpaved tracks that OpenStreetMap access data actually allows you to drive – and turns every trip into an adventure without paper atlases, guesswork or trouble on blocked roads. Signs on the ground always win; the app handles the rest.
🏔️ Terrain over highway
Four route profiles from "shortest" to "maximum unpaved" – you decide how much trail goes into your route.
🚙 4x4, enduro & car
Vehicle profiles for off-roaders, travel enduros and cars respect what your vehicle can actually handle.
⚖️ Legal by design
Access and vehicle restrictions from OpenStreetMap are hard rules – private roads and closures are avoided.
Current features
All of this already works in the web app today – free and usable without an account.
Our own routing engine
Self-hosted GraphHopper backend on OpenStreetMap data with elevation model – no external routing service.
4 route profiles
Shortest, direct, adventure and maximum unpaved – including detour and gravel-share stats.
Real GPS navigation
Turn instructions, remaining time, off-route detection and automatic rerouting – right in the browser.
Climb & descent
30 m elevation model for every route: minimum, maximum, total ascent and descent.
GPX import & export
Export routes as GPX or import existing tracks and ride them.
Community reports
Report and confirm blocked roads – three trusted confirmations and the route avoids them.
