Has anyone else had issues mounting SD card via USB to listen to music on a car stereo? I just installed a Jensen DVD unit that has front and rear USB ports along with auxiliary front and rear. I'm not to sure why someone would need so many ways to hook up a device, but that's not my issue. The issue I have is it seems like my Droid and deck see eachother and both automatically set up to mount the SD card via USB but can not seem to finalize the mount. The deck says disk not ready and my Droid says USB connected. It is the same in froyo and GB roms. I know I could connect via auxiliary but I would like to keep my phone charged while on my way to work, and only connect one wire, if possible.
