All Active 20 GPS units feature powerful "snap-to-track" off-road routing functionality. This makes route-planning on the unit itself, super easy. Just a few clicks and your chosen route will "snap-to-track". Driven by Wi-Fi "hot-spot" connectivity this feature does not require specialist "routable" mapping. As a result, this feature allows global off-road routing, irrespective of the MapCard loaded.
In the UK, this effectively allows full Off-Road Routing for all Ordnance Survey coverage (1:25k & 1:50k) - not just the National Parks - a truely powerful feature.
