Audio out through the micro USB to my car usb input port?

[hal1]

My car has a USB port in the console, but when I attach a charging cable from my Maxx to the USB port my radio simply says "Check Device" The phone does show it's charging.

Is there a setting or separate cable I need, or does the micro-usb to usb not provide audio out. (yes, I know I can use bluetooth or the aux jack)

From what I can figure, the Maxx does not have audio out through USB port, only charging and/or a data connection. Bluetooth or headphone jack only for audio. The Maxx also does NOT do video through that port.

I Wondered about this because I think the Bionic did send audio out the microUSB since that is how the car dock got the audio out.

If you're connecting through the Griffin car dock, it doesn't pass the data through it. Only power. If you connect the phone directly using a USB cable, I believe it should be seen as a storage device.
