I really hope someone is able to get this figured out. I had hopes of outputting google nav turn by turn and pandora to my car speakers. I previously had a Motorola Q which also has a micro usb port and I had purchased a usb micro to stereo mini (3.5) adapter by Motorola and it worked fine on the Q. It doesn't seem to work at all on my Motorola Droid. Seems like all the components are there but maybe Google needs to add this functionality via software...who knows.
