CarPlay (iPhone) — Pair Headset to Your iPhone
For CarPlay users, you only need to pair your helmet headset/intercom with your iPhone.
Put your helmet headset/intercom into pairing mode
On iPhone: Settings → Bluetooth → select your headset/intercom
Confirm the iPhone’s audio output is routed to your headset (and volume is up)
Common Issue:
If you can see the map but hear no voice navigation:
Confirm the headset is paired to your iPhone (not to RiderNav).
Open iPhone Control Center → Audio Output and choose your helmet headset.
Disconnect other Bluetooth audio devices to avoid conflicts.
