ViewRanger GPS came out on top in the Great Outdoors Challenge on Channel 5's The Gadget Show this week.

In the final part of their challenge, Gadget Show presenters, Ortis Deley and Suzi Perry had to navigate their way to the summit of the Pap of Glencoe, with Suzi using a traditional outdoor GPS unit whilst Ortis was kitted out with a Google Nexus One mobile phone equipped with the ViewRanger GPS app with Ordnance Survey topographic mapping.

Suzi was ahead as both presenters entered this final stage of the Challenge. However, Ortis was able to triumph and finish first using the walking routes available for live download within ViewRanger GPS.
