Just got this on Friday and plug it in, works fine - but it doesn't sound good. I had just been using the bluetooth streaming and that sounds 100x better than this $90 cable I wasted my dough on.

Is there something I can do besides returning it that will help it work correctly?

This is what I bought:

USB Y-Cable Audio Connector - Genuine 61122408012

 

Maybe have the signal changed to digital from analog on the ECU
