Help Bluetooth Music Problem

[Dabitz]

Hi everyone... kinda frustrated here. How do I stop the stock music player from automatically start everytime I start a bluetooth connection in my car. I am playing pandora and when I go back to either the stock or Car Home docking apps, the default/stock music player will start playing. Sometimes with I switch to Pandora the player will start as well causing two songs to play at the same time. Any advice?

Thanks as always...
