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.

The connection time varies depending on the car model and smartphone, but on average, the connection is completed within 20 seconds.

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.
