I'm sure this question has been asked but I've been unable to find it. I have a BMW 525 with built in bluetooth, so I already get my calls through my radio. Is there a plug in device that will also play my Droid music over the radio? I have a belkin product that does this for my Ipod but wasn't sure if there was someting for the droid. Clearly, I'm about as technically inclined as this dancing banana:icon_ banana:, so please forgive what is probably a very obvious question. Thank you, thank you! Patty
