When the Bosch integration is active, some of your helmet settings become fixed and can't be customized in the UNIT 1 app. This is expected — it's part of how the integration works.
When your UNIT 1 helmet is set up with the Bosch system, it runs on a special integration mode. To let the helmet and bike work together, certain settings that are normally customizable in the UNIT 1 app become locked to preset values.
The fixed settings are:
Turn Signals
Animation: Blinker - Duration: 10 seconds
Brake Lights
Animation: Solid - Sensitivity: Medium
A few other things you'll notice in the app:
A badge appears on the Home screen showing the connected brand.
The Remote widget is disabled (the Remote can't be customized while the integration is active).
A custom icon shows on the Software Version screen.
Important: This means that even though the bike itself only controls the brake light automatically, connecting through Bosch also locks your turn signal settings to the preset above.
