Sharper Image offers a Belkin "TuneBAse FM transmitter" for theiPod mini. Has anyone tried it? It plugs into the auxiliary outlet under the dash, has a gooseneck tha goes to the receivef, which is alsoa dock for the iPod mini. Wanted to know if it works very wll with the Prius radio (I don't have the preiumium, radio, just the regular one). Thanks.
