The BOSS GX-100 does not have built-in Bluetooth functionality. To connect the GX-100 to a mobile device wirelessly, the BOSS Bluetooth® Audio MIDI Dual Adaptor (BT-DUAL, sold separately) is required.
Note: Bluetooth audio transmission is one-way only, from the mobile device to the GX-100. Refer to "Wireless connection with a mobile device" in the GX-100 Reference Manual for details on connecting the BT-DUAL and Bluetooth audio functionality.
