8. User Tips
- Power Meter Compatibility: While the M1 supports power meters via ANT+, some users have noted that specific power meters might not be immediately available or compatible. Ensure your power meter uses ANT+ and test connectivity.
- Garmin Mount Compatibility: The M1 mount is similar to Garmin mounts, and some users have successfully used Garmin mounts with the M1. However, for optimal fit and security, it's recommended to use the provided CYCPLUS mount or a specifically designed compatible mount.
- Indoor Cycling: The M1 primarily relies on GPS for speed and distance. For indoor cycling or spinning, you would need external speed/cadence sensors (ANT+) to get accurate data, as GPS will not function indoors.
- Language Support: The device's primary language is English. While the manual is multilingual, the device interface is in English.
- Data Accuracy: For precise GPS tracking, ensure the device is in an open area away from obstructions. The speed of positioning can be affected by environment and weather conditions.
