Thanks but the problem is i have a Galaxy S3 and my car cannot read it when its plugged into the USB port.
i think you may have to put the phone into a different usb mode. i have the same phone but don't have usb in my car to try it. but that's how it works when you plug it into the computer you need to tell it it's a media drive so it'll read the right folder structure.
i would assume it would be the same way with a car, maybe someone else can chime in.
