I use the Moto T505 car Bluetooth, works great with the EVO, used it with my diamond before that. It connects to your phone and can play through its own speaker, or with its fm transmitter broadcast through your stereo system in your car. There is an app in the market that turns on Bluetooth when you connect a power source, works well for this as I don't have to remember to turn it on, just plug it in and then turn on the Bluetooth and its synced.

The best thing about the EVo, and I am guessing it will be true with other android phones, the controls on the Bluetooth to skip fwd and back, and play pause seem to work with any media player, including the Pandora and Last FM apps. If you just connect it and press play on the BT it starts playing from the last app used for music. This was not true with windows, it would only work with the htc music player in sense or tflo3d or with windows media player.
