In theory, yes you should be able to utilize a bluetooth enabled usb to stream audio from your phone, but it might be more cost effective to just add a radio with Bluetooth to your device instead. Why does my car stereo sometimes say "read" when my phone is plugged in.
You can find Bluetooth audio receivers with dual USB chargers (4.8A) on various online retailers such as Amazon, Best Buy, Walmart, and eBay. Additionally, electronic stores such as Fry's Electronics or Micro Center may also carry such devices.
There are several bluetooth audio receivers on the market, but the 4.8A model is the best value and will work with most smartphones and devices. You can find it here.
