After revealing the add-on months earlier, Belkin today at last began shipping the TuneCast Auto Live. It remains the first FM transmitter to carry its own iPhone app (free, App Store) and uses this to extend the functionality beyond just the simple in-line remote. It can both expand the controls as well as connect to the Internet to provide feedback on the clearest stations. iPhone owners can also use their GPS to automatically set the transmitter based on location.
