How to open the Bluetooth of the stereo

First open the stereo, and then open the Bluetooth on your phone to find the Bluetooth device password is generally available on the manual, paired up you can hear a beep. Finally you can play music or movies/TV shows on your phone.

The Bluetooth master device can communicate with up to seven devices in a wired network (a temporary computer network using Bluetooth technology), although not all devices can reach this maximum number. Devices can switch roles via the protocol, and slaves can switch to masters (e.g., if a headset initiates a connection request to a cell phone, it is naturally the master as the initiator of the connection, but may then function as a slave.)
