Hi Adam,
1) I had an Alpine INA-W900E Navteq, DVD, iPod,iPhone & Bluetooth. It worked perfectly but it wasn't cheap. Installed in my BsB V-Spec II.
2) My EVO 8 has a new Android Parrot Smart. Bluetooth can connect with 2 phones simultaneously. Voice Command is terrific. Volume control is easy via swiping the screen. Picture quality is good. Half the price of others. You're welcome to try mine out whilst at the Putty meet.
