My car doesn't have a user accessible AUX port, so I'm stuck going the FM transmitter route. Complicating matters, I live in Silicon Valley where the spectrum is jam-packed. I tried the Belkin tunebase, but it was so weak and "static-y" as to be non-functional. I've read here that Belkin tunecast is suspect as well. Anyone have any recommendations for a GOOD FM transmitter for the 3G.
