Satellite Navigation: Lost And Found

A purpose-built sat-nav system for 4x4 use guarantees continent-wide coverage.

Most vehicles bought from the showroom floor these days come with an embedded satellite-navigation system of some sort – of varying levels of competency. The problem when it comes to our lifestyle is that manufacturer sat-nav systems will lack the functions and features for proper off road use. Sure, some will come with off-road features, but for guidance when it comes to ‘real’ off roading you need to trawl the aftermarket industry.

“As any keen four-wheel driver will understand, stock vehicles are a great base to build upon for a more purpose-specific off-road setup,” explained Adam Jane, editor at HEMA Maps. “In the same way that drivers might wish to upgrade to more capable tyres, suspension and lighting, it’s often a good idea to step up from the generic in-car GPS system to something purpose built.”

A purpose-built sat-nav system for 4x4 use will feature topographical maps (detailed and accurate two-dimensional representations of features on the Earth’s surface), precise mapping of remote tracks and the ability to function when off-the-grid – as well as a bunch of useful tools like POIs (point-of-interests), the ability to sync waypoints and save favourite off-road routes.
