Yet another issue I had with this device was the output level. Ideally, I would want the device to broadcast at the same volume level as the radio stations around, so if you change the channel, you are not blasted by sound. Unfortunately, it doesn't. In fact, to broadcast at the same volume level as local radio stations, I have to turn my Treo's output down to the point where it wouldn't distort the input and turn up the car stereo to the point where I am starting to hear the engine's electrical interference. If I were to use the USB port to power my Treo while broadcasting via the audio input, the interference is worse.
