that's really neat, I got nearly half way through the video (linked on Ricks site), and am thinking that it's actually fairly complicated.
The bluetooth is nice, as is the aux in, but the usb seems rather pointless unless you want to listen to the same play list over, and over again;
In my opinion, you need a screen, and a way to change tracks to really optimize a usb player.
if you do this conversion, aren't you also not able to go back to the original radio, since it appears as though the original radio more or less gets gutted?
Maybe I am misunderstanding the conversion??
