>I am wondering what you use the serial connector for while in the car?

To upgrade the firmware. As it is now, I can use my laptop to upload music, but that dumb connector swap means I'll need an adaptor.

Really, the interface should work exactly like a car stereo should - menus, for example, should *time out*. As for velco-ing anything, I can't imagine anything quite as ugly as a velco strip on my dashboard. I'll figure something out.
