Built-in Dual Bluetooth
Portable apple carplay screen built-in dual bluetooth, pair your phone to the carplay touch screen via Bluetooth, pair the unit to your Bluetooth helmet/earphone, then you can adjust the volume/switch songs, and make hands-free calls by your helmet or earphone, so easy.
This apple carplay screen supports most of the Bluetooth headsets on the market, but it does not support the modified team intercom Bluetooth headsets and helmets (everyones modification scheme is different, we cannot support it), no matter whether they are connected or not, they cannot be used.
