just wondering if anyone has tried this. I have an fm modulator that can take an input from an mp3 player or cd player, or anything with an audio output on a standard audio jack, and output an fm signal that can be tuned in on the radio. I am thinking to take the stereo adapter and use it to plug a double ended male audio cable to the fm modulator, and in doing so that would make my car stereo the speaker output for the phone. Then take the treo and use a phone holder so that the microphone is pointing in my general direction.

Has anyone already tried this?
