All functions are easily and directly accessible.
The day's route can be reset directly with a short hold a key. Class.
The built-in lighting comes in handy in the dark.
The temperature display is also very nice and is often used by me.
The speedometer is mounted quickly and easily. Cable along the handlebars down wrap finish. (So why pay more for radio)
The Sigma works pretty much and I had compared with GPS hardly KM variations in my tracks.
Conclusion:
So the biking is even more fun. Great features for a reasonable price. Class
