Thanks to ANT+ and BLE, it is possible to connect external sensors such as speed, heart rate, and cadence sensors. Smart Notifications keep you in touch with the outside world during your ride by notifying you about incoming calls and messages on the display. A graphical elevation profile can also be accessed on the ROX 4.0 Endurance. The starting elevation at the beginning of the tour can be automatically calibrated via GPS or set manually. With the Search and Go navigation, any location can be quickly found and navigated to. During navigation, the track and turn-by-turn directions are displayed.
