I couldnt seem to figure this out on my own. Does the Evo car charger allow music to be played through the speakers, or is it purely for charging? Not too sure about this but i found this link so thats why im wondering. Amazon.com: HTC EVO 4G Car Charger: Cell Phones & Service it says that it can play music. thinking about getting a BT but if this charges and plays music then i dont need one, ill just stick with the charger.
