Global Critique
“The navigation function is easily the best feature of the ROX 12.0. It comes with 20 European country maps preinstalled, and I was very impressed with the speed it loads, zooms and finds routes — many other GPS computers need more time.”
“Sigma claims a battery life of up to 16 hours; during my test, with navigation on, it reached a critical point at around 12. The touchscreen works extremely well and can even be read in direct sunlight.”
“Draw my Route works extremely well — sketch a rough loop on the map and in seconds the ROX gives you three routes to ride based on your rider profile.”
“I never had a single issue with the performance throughout testing. The navigation and tracking accuracy are superb — a cracking unit that covers pretty much every base.”
