[HTC FORTRESS WM6.5]

From what I experienced its output cannot be amplified through aux input. This is obvious when you try to turn up the volume on your audio system. All audio output via aux (3.5mm jack) is fixed to the system volume on the playback device. In other words its for headphones not audio systems .. Sorry. What we need is a mini USB to USB With the proper firmware on the other end that can accept streaming. My car stereo does not recognize the ppc as an Ipod only as an external drive.
