Can only one smartphone be connected?
You can connect multiple smartphones to one device. However, simultaneous use is not possible, and the most recently connected smartphone takes priority. Therefore, if more than one smartphone is registered with the device, it's recommended to disable Wi-Fi and Bluetooth on smartphones that you do not wish to connect to ensure a smooth connection.
How long does it take to connect the device?
The connection time varies depending on the car model and smartphone, but on average, the connection is completed within 20 seconds.
How does the connection work?
AA(Android Auto)
The connection is established using Wi-Fi and Bluetooth. The initial connection is made via Bluetooth, and then information is transmitted through Wi-Fi. Therefore, do not turn off Wi-Fi or Bluetooth during use.
DeX(AutoPro X)
The connection is established using Wi-Fi Direct. If Wi-Fi is disabled during use, the connection may be terminated.
What Wi-Fi frequency is used?
It uses 5GHz Wi-Fi.
