Connects easily with my wife's Palm Pre for both Hands-Fee phone operation and music (A2DP) streaming. The strength of the FM transmitter is decent enough if your home market isn't crowded, but its not for the traveler. Instead, my wife mainly uses the speaker for both calls and music streaming, which is plenty loud. At the price, its almost more reasonable to get a new head unit with bluetooth built in, as they are certainly cheap enough these days.
