I'm getting a new car stereo next month, and I'm thinking about getting one with a USB input in it. Has anyone used their Droid like this before? It'd be great if I didn't have to run Droid charging cable all the way to car power port, but I'd like to make sure it works before buying one. Also, would a stereo be able to browse the folders on the microSD, like a computer? That would be awesome.
