The systems are based on the ANT + standard, therefore the sensors of the ROX 10.0 GPS and ROX GPS 11.0 can be connected to the ROX 12.0 SPORT.

ANT + sensors from other manufacturers can be connected to the ROX 12.0.

To perform a firmware update, please proceed as follows:

1. Start your ROX 12.0 SPORT

2. Make sure that you are connected to a Wifi network

3. Connect your ROX 12.0 SPORT to a power adapter using the micro USB cable

4. Now wait a few minutes for the update to load in the background (an arrow appears next to the time display)

5. Confirm the message "New software update available" with the green button "Now"

6. Then wait until the installation has been completed and the ROX 12.0 SPORT is restarted

To do this, select: “My Activities” -> “Select one” -> “Options (start as track)” -> “Options” -> “Save as Track”.

The ROX12.0 SPORT calculates the current speed using GPS. Alternatively, an ANT+ speed transmitter can be used for this purpose. Moreover, it is possible to link an ANT+ heart rate transmitter and an ANT+ cadence transmitter.

In addition to SIGMA's own brackets, third-party brackets marked "K-EDGE" can also be used.

The brackets ROX 11.0 GPS, ROX 7.0 GPS and Pure GPS are compatible with the ROX12.0 SPORT.

The SIGMA CLOUD transfers your activities, sports profiles, tracks and device settings.

Maps of the following countries can be expanded: Africa, Asia, Europe, North America, Oceania and South America. External third-party maps are not expandable.

Yes, please open the settings -> "Map" -> "Map Orientation"

The display can be switched off while driving. Navigation and turn-by-turn instructions are still active. A complete switch off is not possible.
