A route, not a pile of tracks
NavX4 is not a trail database but a navigation app. Enter a start and a destination, pick a profile and get a continuous route. Four profiles range from fast on tarmac to maximum unpaved. Add stops, compare alternative routes, or let NavX4 build a loop from where you are, by distance or driving time, with the gravel share and direction you want.
Every route shows distance, driving time, elevation profile, gradients, the mix of surfaces and the lowest vehicle class the route needs according to the data.
What your vehicle cannot handle stays out of the route
- Vehicle profile: car, 4x4 and adventure motorcycle.
- Vehicle class: road, raised, all wheel drive or extreme. Roads that need a higher class according to the map are not suggested.
- Dimensions: height, width, length, weight and axle load block roads with a mapped restriction. Where the map has no value, the road is unchecked, not cleared.
- Avoid: fords, villages, private roads, tolls, motorways and ferries, each on its own switch.
Access rules belong in the calculation
NavX4 reads mapped bans and permissions, including time rules such as winter closures, against your departure time. Barriers and bollards are taken into account. For 37 countries NavX4 carries rules on driving in forests, fields and on unpaved roads, each with its legal source, and shows them for every country the route touches. For Great Britain that includes the rules on driving off the road.
On the road
The Android app on Google Play guides you with turn instructions, voice prompts and automatic rerouting, also while the display is off. It shows speed, the speed limit from the map and the vehicle tilt from the phone sensors. Android Auto is part of the Google Play version; not yet in a real car, so far only tested on the Google simulator.
Offline packages with map and place search cover 384 regions worldwide, with routing in Europe as well. You can also plan in the browser at navx4.app.
What NavX4 does not do
- There is no iPhone app, only Android and the browser planner.
- NavX4 does not guarantee that a road is legal or passable. It is a planning aid based on OpenStreetMap.
- Online routing covers Europe only.
- NavX4 is in Early Access: free, a one-person project and not finished.
Frequently asked questions
What is a good offroad navigation app for a 4x4?
For a 4x4 you need navigation that joins unpaved roads into a route on its own and respects access rules, vehicle class and dimensions. NavX4 does this with OpenStreetMap data, free as an Android app and in the browser.
Is there a free offroad navigation app?
Yes. NavX4 is free, with no subscription and no ads. Planning and navigating work without an account; a free account is needed to sync across devices, for the community and for points.
Does NavX4 know the green lanes in the UK?
NavX4 routes on OpenStreetMap data and reads the access tags mapped there, and it carries the British rules on driving off the road with their legal source. Whether a lane is open to motor vehicles is decided by the official records and the signs on site, not by the app.
Can I import GPX tracks?
Yes. NavX4 imports and exports GPX in the Android app and in the browser. You can show an imported track, compare it with a freshly calculated route and follow it in the app.
Is NavX4 available for iPhone?
No. NavX4 is an Android app on Google Play and a planner in the browser at navx4.app. There is no iPhone app.
