can't seem to find an answer on here about how to actually play music through bluetooth on my car stereo. i have my phone and head unit paired but can't seem to understand how to get the music to actually play through the head unit. if i try and play music on the phone (either with the htc music app or mixzing) the sound just comes out of the phones speaker. all the threads on here seem to make it out as its a simple thing to do. my head units owners manual doesn't cover using bluetooth to stream music just how to make/recieve calls.
