BSD (Blind Spot Detection) alerts are emitted directly from the CHIGEE Display unit and are not transmitted to your helmet, Bluetooth headset, or intercom system.

Helmets, Bluetooth headsets, and intercoms connect to your smartphone via Bluetooth and are designed to carry phone audio only (such as calls, music, or navigation prompts). BSD alerts, however, are a safety feature built into the CHIGEE Display itself. For this reason, the alerts are played only from the display’s onboard speaker, ensuring they are always audible regardless of your phone or headset connection status.

This design makes BSD alerts reliable and independent from external audio devices, so you will not miss a warning even if your headset is disconnected or your intercom is turned off.
