I just got my Samsung Fascinate with the car dock manufactured by Samsung as a replacement from Motorola Droid. I didnt know that the dock has a 3.5mm audio out on the back that connects thru a slider unit that inserts into the Samsung's micro USB port so I was excited that I only had to connect one thing for both power and audio. The only problem is that there is no audio coming out of the port and no where on Samsung's website nor Verizon, does it mention that the docks had audio out going from the micro USB plug that input for power and out for audio. I am not sure if it was mistake in manufacturing or if I got a DOA. Please, if anybody has this same issue, let me know if you are having the same problem.
