I've been wanting to play music through my cars speakers (2006 GP base with monsoon) ever since I got it. I've been researching some and bought this

Little did I know, it didn't work if you didn't have an external CD player or XM. I read somewhere about there being a module with bluetooth and being able to replace the onstar with it. I don't mind the onstar, but if it has to go it will go. I want to be able to have a way to play music through this car whether it be via bluetooth or auxillary cord without spending big $$$. Does anyone have any suggestions?
