OK it can't be used anywhere but in the car but we only know the benefits cause we have one that can. You don't miss what you don't know about.

Add wireless ethernet via the USB port and build a small wireless box with RCA jacks to stream to and you could turn up at parties with your car parked outside and stream music inside... :) Or maybe take it one step further and make the remote unit small enough to run off batteries and stream from your car to a personal unit with headphones and continue listening to your music while shopping... *grin*
