Let me explain more detail about "Superior Track Back".
When you active "Track Back" in record menu, system will auto compress trace by specific algorithm. So it allows you follow up with any speed.
We also enlarge the road and point to easier for look. For sure, it is without landscape map.
For Quechua, when you plan the route on Map from PC Software, the landscape map and route will both download to device. It will guide you more accurate.
The application is more suitable for hiking and adventuring.
