This is a restart of an old thread. There are so many more members since the last time I asked this question. I need a AUX adapter to allow any audio connection to the stock stereo. It must be possible to manufacturer. Honda makes an OEM DVD and MP3 player that has the circuitry to connect to the stock stereo. I want to connect my Pocket PC/Phone/MP3/navigation system. I have tried to use two different FM modulators with very poor audio quality. Any ideas or new adapter product out there?
