I'm about ready to convert over to an HTC Droid Incredible from my iPhone and I was wondering if anyone has tried connecting a droid phone to a Pioneer head unit via USB and how much functionality you get. Does the head unit get audio from the USB? Or is it just for charging? I'd be happy with just getting audio through USB but I know right now the iPod interface cable has the separate 3.5mm jack that plugs into the HU. Thanks for any info.
