BNS 5.0 Bluetooth, Power and Ground wires

[paiNsage]

Hello, i wanted to put a bluetooth streaming device in my A3 with BNS 5.0. The streaming device has 3 wires for the AUX and 2 more for power and earth. Where do i plug these two in for the BNS? I can't find the points in the pinout for power and ground, any help?
Thanks

Wire to fuse for 12v ignition on or to cigarette lighter if you want it to never turn off and kill your battery, earth it to a stereo screw
