The firewire port is NOT used to power the iTrip, it is just a piece of plastic there that holds it in place. The iTrip is actually powered by the sound port (where the remote control is usually powered). Griffin will probably make one for the new iPod, but as kendall says probably not for awhile, and this time they will have to make it so it powered by the power/gnd in the bus on the bottom of the new ipod, this is better actually because it is getting cleaner sound from line-out, and you don't loose the headphone port. But yes, FM transmitters aren't the way to go if you want amazing sound, invest in a AUX-out headunit and run a RCA from the AUX in to the LINE OUT on the ipod dock, mount the dock somewhere in your car, and you're golden. I'll post pics of my integration later tonight.
