1. Ensure both the OnelapFit app and the bike computer are running the latest versions.
2. Map files can only be downloaded via Wi-Fi. We recommend connecting to a stable home or office network and avoiding public Wi-Fi with frequent interruptions.
3. Do not switch modes, restart, or power off the bike computer during download, as this may corrupt the file.
4. Downloaded map files are exclusively compatible with the C706 bike computer and cannot be transferred between devices (for example, copied to other C606 series bike computers).
5. If download failures occur ≥3 times, check Wi-Fi signal strength and try moving the bike computer closer to the router.
6. Cross-border map download rules: a. Schengen Area: Supports selecting and downloading map files across multiple countries. b. Non-Schengen Area: When selecting an area across multiple countries, the system will automatically download the map file of the country with the largest geographic coverage within the selected area.
7. For additional download considerations, refer to the help page in the upper-right corner of the map download interface.
