NaxaElectronics NAB-4003 Wireless Audio Adapter with Bluetooth for USB Connectors (Black)

will this allow me to connect to play any audio from my android smartphone (eg. music from my spotify app) on my windows 10 pc speakers?

(2011 G37x non nav) when I plugged it in and paired my phone, on the car screen is says device not readable. Anyone know why?

If i connect it to a speaker can i find it with my phone

Well this work on an Infinty g37 coupe?
