FAQs

Do I need any additional hardware to pair my Shimano Di2 with my Garmin Edge 830?
Yes, you'll need an appropriate Shimano Di2 junction box (e.g., EW-WU111) that is compatible with ANT+ wireless communication. This junction box acts as the bridge between your Di2 components and the Garmin Edge 830.
My Shimano Di2 and Garmin Edge 830 are paired, but I'm not seeing gear information on my Edge 830. What should I do?
First, ensure that both devices are powered on and within range. Check that the ANT+ setting is enabled on your Edge 830. Then, go to the sensor settings on your Edge 830 and check if the Di2 is correctly recognised and that gear display is enabled in the data fields. If the problem persists, try a soft reset on both the Garmin and Di2 system.
What information about my Shimano Di2 system will the Garmin Edge 830 display?
Typically, you'll see your current gear (e.g., 34-28), battery level of your Di2 system, and potentially the chainring and cassette combination selected. The exact data displayed may depend on your specific Di2 groupset and Garmin Edge 830 firmware versions.
