I don't have the tech package, but I am wondering if there is a way to unlock the ability to stream music from my phone without using the USB cable. I mean it already has phone call bluetooth integration already.

 

Try one of the audio shops in your area. They may be able to tap into the hidden features if there are any.

You can purchase any Bluetooth streaming device that has the capabilities of connecting through USB or through the RCA jacks. Look for aptX capable devices, these are the currently the highest quality bitrate for audio streaming so you will not degrade the audio quality if you plan to stream through Bluetooth. You'll also want to find one that will auto-connect to your phone, so you don't have to open the center arm rest storage every time to turn on the device to stream your music.
