so my car has a usb slot in the glove box. is there a way that I can make a device that has a built in wifi connection or something and make it so I see the device on my network, and can just drag and drop music into whatever device I would need, so that i can then listen to the music in my car? Without needing to constantly transfer the device back and forth? I guess it'll need a battery too or something? not sure if this will be possible :\
